The sdHawkes model consists of an oracle Hawkes process and a state process following Markov transition.

On one hand, work based on \u0026quot;probing classifiers\u0026quot; generally suggests that SOTA\u0026nbsp;language\u0026nbsp;models contain rich information about\u0026nbsp;linguistic\u0026nbsp;structure (e.g., parts\u0026nbsp;of\u0026nbsp;speech, syntax, semantic roles).

Yet, as a result MDPs lack structure and as such planning and learning in MDPs with the typically enormous state and action spaces is strongly intractable; no algorithm can avoid Bellman\u0026#39;s curse of dimensionality in the worst case. However, as recognized already by Bellman and his co-workers at the advent of our field, for many problem of practical interest, the optimal value function of an MDP is well approximated by just using a few basis functions, such as those that are standardly used in numerical calculations. As knowing the optimal value function is essentially equivalent to knowing how to act optimally, one hopes that this observation can be turned into efficient algorithms as there are only a few coefficients to compute. If this is possible, we can think of the resulting algorithms as performing computations with a compressed form of the value functions. While many algorithms have been proposed as early as in the 1960s, until recently not much has been known about whether these compressed computations are possible and when. In this talk, I will discuss a few recent results (some positive, some negative) that are concerned with these compressed computations and conclude with some open problems.

Today, AI researchers \u0026amp; practitioners increasingly use deep neural networks for many applications across different modalities and areas such as NLP, Vision, Speech, Conversational and Multimodal AI. However, much of the Deep Learning revolution has been limited to the Cloud and highly specialized hardware. Recently the AI community has witnessed an increasing trend for training larger and larger neural models (e.g., GPT-3, T5, BERT) that achieve state-of-the-art results but require enormous computation, memory and energy resources on the Cloud. In order to enable AI experiences in real-time across all users and devices, ML models have to run efficiently on the Cloud and personal devices on the Edge (e.g., mobile phones, wearables, IoT) which have limited computing capabilities.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn this talk, I will introduce our work on Neural Projection computing, an efficient AI paradigm, and a family of efficient Projection Neural Network architectures that yield fast (e.g., quadratic speedup for transformer networks) and tiny models that shrink memory requirements by upto 10000x while achieving near state-of-the-art performance powering vision and NLP applications on billions of mobile devices. Widespread increase in availability of connected \u0026ldquo;smart\u0026rdquo; appliances (e.g., conversational assistants) means that there is an ever-expanding surface area for mobile intelligence and ambient devices in homes.

For the case in which the noise is identically distributed, we derive the exact asymptotics via the use of probabilistic tools from the theory of strong large deviations. Our results strictly improve those of Bresler and Karzand (2020) and Nikolakakis et al. (2019) and demonstrate keen agreement with experimental results for sample sizes as small as that in the hundreds. When the noise is non-identically distributed, Katiyar et al. (2020) showed that although the exact tree structure cannot be recovered, one can recover a \u0026quot;partial\u0026quot; tree structure; that is, one that belongs to the equivalence class containing the true tree. We propose Symmetrized Geometric Averaging (SGA), a statistically robust algorithm for partial tree recovery. We provide error exponent analyses and extensive numerical results on a variety of trees to show that the sample complexity of SGA is significantly better than the algorithm of Katiyar et al. (2020). SGA can be readily extended to Gaussian models and is shown via numerical experiments to be similarly superior.\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\n\u003Ca href=\u0022https:\/\/nam12.safelinks.protection.outlook.com\/?url=https%3A%2F%2Farxiv.org%2Fabs%2F2101.08917\u0026amp;data=04%7C01%7Callie.mcfadden%40cc.gatech.edu%7Cc6863e90d4b4494351c808d8c3310f58%7C482198bbae7b4b258b7a6d7f32faa083%7C0%7C0%7C637473962801816192%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000\u0026amp;sdata=ZTmvfmgM%2BxcUYkVKwN%2FZYFnY7E8HY8rZx2VsbiLWN3U%3D\u0026amp;reserved=0\u0022\u003Ehttps:\/\/arxiv.org\/abs\/2101.08917\u003C\/a\u003E\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\n\u003Ca href=\u0022https:\/\/nam12.safelinks.protection.outlook.com\/?url=https%3A%2F%2Farxiv.org%2Fabs%2F2005.04354\u0026amp;data=04%7C01%7Callie.mcfadden%40cc.gatech.edu%7Cc6863e90d4b4494351c808d8c3310f58%7C482198bbae7b4b258b7a6d7f32faa083%7C0%7C0%7C637473962801816192%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000\u0026amp;sdata=OsXoKiYjXR17Hflt4BaHuB7TCdwY23Er1E0LJuwJcJ8%3D\u0026amp;reserved=0\u0022\u003Ehttps:\/\/arxiv.org\/abs\/2005.04354\u003C\/a\u003E\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\nThis is joint work with Anshoo Tandon, Aldric J.

First, I\u0026rsquo;ll present a model capable of filling in missing parts in ancient cuneiform tablets written thousands of years ago in now-extinct languages (Akkadian and Sumerian). Due to deterioration over time, these excavated tablets are often broken, faded, or cracked, making it hard for historians and archaeologists to read and interpret them. We show that by leveraging large-scale language models pretrained on modern texts we achieve good results in restoring missing parts in various domains and time periods, in the automatic evaluation as well as human analysis. Second, I will discuss a novel document-level representation of wet lab biochemistry protocols geared towards experiment automation and reproducibility, addressing challenges such as cross-sentence relations, long-range coreference, grounding, and implicit arguments. I\u0026rsquo;ll show examples from a manually-annotated corpus of complex lab protocols, and\u0026nbsp;present graph-prediction models that form the first step towards fully executable lab protocols.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EDr.\u0026nbsp;Gabriel Stanovsky is a senior lecturer (\u0026asymp; assistant professor) at the Hebrew University of Jerusalem.

Developing robust and real-time computational tools for assisting critical care in the intensive care units (ICUs) is particularly of great value because of the high cost (taking about 15-20% of hospital budgets) of the care, high mortality rate (ranging from 8-19% or about 500,000 deaths annually) in the units, and the extremely large detailed data that have been collected but mostly wasted. That is, an overwhelming amount of devices such as vital sign monitors, mechanical ventilators, dialysis machines, etc, are often used in the ICUs to monitor all aspects of patients, but even the most experienced and knowledgeable intensivists hardly can understand such massive information on a continuous basis. Thus we have completed works on developing dynamic machine learning models and recurrent neural networks that can accurately detect patient deterioration and serve feedbacks in real time from integrating the large amount of multimodal continuous monitoring data.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn this proposal, we focus on developing robust detection methods that customize reliable feedbacks based on individual patients. We propose two ways to achieve the goal: model calibration and personalized thresholding. With the proposed scalable calibration method, our model can generate reliable confidence scores that can be later used for raising alarms only if the prediction confidence is high. Combining with the proposed personalized thresholding method, these generated alarms can be customized and take account of the trade-off between early detection and low false alarm rates.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Machine Learning Ph.D. student Yanbo Xu will defend her thesis proposal."}],"uid":"34773","created_gmt":"2021-01-08 14:18:46","changed_gmt":"2021-01-12 14:19:49","author":"ablinder6","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2021-01-12T13:30:00-05:00","event_time_end":"2021-01-12T15:00:00-05:00","event_time_end_last":"2021-01-12T15:00:00-05:00","gmt_time_start":"2021-01-12 18:30:00","gmt_time_end":"2021-01-12 20:00:00","gmt_time_end_last":"2021-01-12 20:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"47223","name":"College of Computing"},{"id":"37041","name":"Computational Science and Engineering"},{"id":"576481","name":"ML@GT"},{"id":"50877","name":"School of Computational Science and Engineering"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"177814","name":"Postdoc"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EStephanie Niebuhr\u003C\/p\u003E\r\n\r\n\u003Cp\u003Estephanie.niebuhr@cc.gatech.edu\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"642596":{"#nid":"642596","#data":{"type":"event","title":"ML@GT Virtual Seminar: Sanjeet Hajarnis, eightfold.ai","body":[{"value":"\u003Cp\u003EML@GT will host a virtual seminar featuring Sanjeet Hajarnis, a principal engineer at eightfold.ai.

Our method smartly utilizes the expressive ability of neural networks in a multi-task learning framework merged with our `Unrolled Algorithms\u0026#39; technique.

Techniques for representing individual channels, such as visual data or textual data, have greatly improved, and some techniques exist to model the relationship between channels that are \u0026ldquo;mirror images\u0026rdquo; of each other and contain the same semantics. However, multimodal data in the real world contains little redundancy; the visual and textual channels \u003Cem\u003Ecomplement\u003C\/em\u003E each other. We examine the relationship between multiple channels in complex media, in two domains, advertisements and political articles.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EFirst, we collect a large dataset of advertisements and public service announcements, covering almost forty topics (ranging from automobiles and clothing, to health and domestic violence). We pose decoding the ads as automatically answering the questions \u0026ldquo;\u003Cem\u003EWhat\u003C\/em\u003E should do viewer do, according to the ad\u0026rdquo; (the suggested \u003Cem\u003Eaction\u003C\/em\u003E), and \u0026ldquo;\u003Cem\u003EWhy\u003C\/em\u003E should the viewer do the suggested action, according to the ad\u0026rdquo; (the suggested \u003Cem\u003Ereason\u003C\/em\u003E). We train a variety of algorithms to choose the appropriate action-reason statement, given the ad image and potentially a slogan embedded in it. The task is challenging because of the great diversity in how different users annotate an ad, even if they draw similar conclusions. One approach mines information from external knowledge bases, but there is a plethora of information that can be retrieved yet is not relevant. We show how to automatically transform the training data in order to focus our approach\u0026rsquo;s attention to relevant facts, without relevance annotations for training. We also present an approach for learning to recognize new concepts given supervision only in the form of noisy captions.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ESecond, we collect a dataset of multimodal political articles containing lengthy text and a small number of images. We learn to predict the political bias of the article, as well as perform cross-modal retrieval despite large visual variability for the same topic. To infer political bias, we use generative modeling to show how the face of the same politician appears differently at each end of the political spectrum. To understand how image and text contribute to persuasion and bias, we learn to retrieve sentences for a given image, and vice versa. The task is challenging because unlike image-text in captioning, the images and text in political articles overlap in only a very abstract sense. We impose a loss requiring images that correspond to similar text to live closeby in a projection space, even if they appear very diverse purely visually. We show that our loss significantly improves performance in conjunction with a variety of existing recent losses. We also propose new weighting mechanisms to prioritize abstract image-text relationships during training.\u003C\/p\u003E\r\n\r\n\u003Ch3\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003C\/h3\u003E\r\n\r\n\u003Cp\u003EAdriana Kovashka is an Assistant Professor in Computer Science at the University of Pittsburgh.

Machines can recognize objects in images and translate text, but they must be trained with more images and text than a person can see in nearly a lifetime.\u0026nbsp;\u0026nbsp;The computational complexity of training has been offset by recent technological advances, but the cost of training data is measured in terms of the human effort in labeling data. People are not getting faster nor cheaper, so generating labeled training datasets has become a major bottleneck in ML pipelines.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EActive ML aims to address this issue by designing learning algorithms that automatically and adaptively select the most informative examples for labeling so that human time is not wasted labeling irrelevant, redundant, or trivial examples. This talk explores the development of active ML theory and methods over the past decade, including a new approach applicable to kernel methods and neural networks, which views the learning problem through the lens of representer theorems. This perspective highlights the effect that adding a given training example has on the representation.\u0026nbsp;\u0026nbsp; The new approach is shown to possess a variety of desirable mathematical properties that allow active learning algorithms to learn good classifiers from few labeled examples.\u003C\/p\u003E\r\n\r\n\u003Ch4\u003EAbout Robert:\u003C\/h4\u003E\r\n\r\n\u003Cp\u003ENowak\u0026nbsp;holds the Nosbusch Professorship in Engineering at the University of Wisconsin-Madison, where his research focuses on signal processing, machine learning, optimization, and statistics.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Nowak will give a virtual seminar as a part of the ML@GT Seminar Series."}],"uid":"34773","created_gmt":"2020-08-13 15:25:38","changed_gmt":"2020-09-29 13:36:01","author":"ablinder6","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-10-07T13:15:00-04:00","event_time_end":"2020-10-07T14:15:00-04:00","event_time_end_last":"2020-10-07T14:15:00-04:00","gmt_time_start":"2020-10-07 17:15:00","gmt_time_end":"2020-10-07 18:15:00","gmt_time_end_last":"2020-10-07 18:15:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"47223","name":"College of Computing"},{"id":"37041","name":"Computational Science and Engineering"},{"id":"1299","name":"GVU Center"},{"id":"589608","name":"Machine Learning"},{"id":"576481","name":"ML@GT"},{"id":"431631","name":"OMS"},{"id":"50877","name":"School of Computational Science and Engineering"},{"id":"50875","name":"School of Computer Science"},{"id":"50876","name":"School of Interactive Computing"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"177814","name":"Postdoc"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EAllie McFadden\u003C\/p\u003E\r\n\r\n\u003Cp\u003ECommunications Officer\u003C\/p\u003E\r\n\r\n\u003Cp\u003Eallie.mcfadden@cc.gatech.edu\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"637558":{"#nid":"637558","#data":{"type":"event","title":"ML@GT Virtual Seminar: Kazoo Sone and Pradyumna Narayana, Google","body":[{"value":"\u003Cp\u003EKazoo Sone and Pradyumna Narayana, software engineers at Google will give a virtual seminar on machine learning on September 23, 2020.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003ERegister at:\u0026nbsp;\u003Ca href=\u0022https:\/\/primetime.bluejeans.com\/a2m\/register\/rujhjqhe\u0022\u003Ehttps:\/\/primetime.bluejeans.com\/a2m\/register\/rujhjqhe\u003C\/a\u003E\u003C\/p\u003E\r\n\r\n\u003Ch4\u003ETitle:\u003C\/h4\u003E\r\n\r\n\u003Cp\u003EMachine Learning Challenges at Google Ads\u003C\/p\u003E\r\n\r\n\u003Ch4\u003EAbstract:\u003C\/h4\u003E\r\n\r\n\u003Cp\u003EWhile we have made significant advances in the last two decades, serving the most relevant ads to our users is still a big challenge to date.

This talk with discus structural properties \u0026ndash; shared by several canonical control problems \u0026ndash; that guarantee the policy gradient objective function has no suboptimal stationary points despite being non-convex.

Despite this, there is much progress needed to deploy deep learning in safety critical applications (such as autonomous aircraft).\u0026nbsp; This is because current deep learning systems are not robust to real-world nuisances (e.g., viewpoint, illumination, partial occlusion).\u0026nbsp; In this talk, we take a step in constructing robust deep learning systems by addressing the problem that state-of-the-art Convolution Neural Networks (CNN) classifiers and detectors are vulnerable to small perturbations, including shifts of the image or camera.\u0026nbsp; While various forms of specially engineered\u0026nbsp;\u0026ldquo;adversarial perturbations\u0026rdquo; that fool deep learning systems have been well documented, modern CNNs can surprisingly change classification up to 30% probability even for simple 1-pixel shifts of the image.\u0026nbsp;This lack of translational stability seems to be partially the cause of \u0026ldquo;flickering\u0026rdquo; in state-of-the-art object detectors applied to video.\u0026nbsp; In this talk, we introduce this phenomena, propose a solution, prove it analytically, validate it empirically, and explain why existing CNNs exhibit this phenomena.\u003C\/p\u003E\r\n\r\n\u003Ch3\u003EBio\u003C\/h3\u003E\r\n\r\n\u003Cp\u003EGanesh Sundaramoorthi is currently Principal Research Scientist at\u0026nbsp;\u003Ca href=\u0022http:\/\/www.utrc.utc.com\/\u0022\u003EUnited Technologies Research Center\u003C\/a\u003E\u0026nbsp;in East Hartford, CT, USA, conducting research in computer vision and machine learning, and building products in robotic inspection from this research.

It is well recognized that, a careful balance of local computation and global communication\u0026nbsp;is necessary to fully unleash the benefits in the distributed setting. In this talk, we first consider a natural framework for distributing popular stochastic variance reduced methods in the master\/slave setting, and establish its convergence guarantees under simple and intuitive assumptions that capture the effect of local data heterogeneity. Next, we move to the decentralized network setting, where each agent only aggregates information from its neighbors over a network topology. We discuss challenges and solutions to obtain decentralized counterparts for algorithms originally developed for the master\/slave setting, and highlight the resulting algorithms using approximate Newton and stochastic variance-reduced local updates. Theoretical convergence guarantees and numerical evidence are provided to demonstrate the appealing performance of our algorithms over competitive baselines, in terms of both communication and computation efficiency.\u003C\/p\u003E\r\n\r\n\u003Ch3\u003EBio\u003C\/h3\u003E\r\n\r\n\u003Cp\u003EDr. Yuejie Chi received the Ph.D. degree in Electrical Engineering from Princeton University in 2012, and the B.E.

Predicting the structure of a protein without similar experimental structures is very challenging and usually needs a large amount of computing power.\u0026nbsp; This talk will present the deep learning method (i.e., deep convolutional residual neural network) we have invented for protein contact and distance prediction that won the CASP (Critical Assessment of Structure Prediction) in both 2016 and 2018 in the category of contact prediction. In this\u0026nbsp;talk\u0026nbsp;we show that by using this powerful deep learning technique, even with only a personal computer we can predict the structure of a protein much more accurately than ever before. In particular, we predicted correct folds for the 3 largest hard targets (~350 amino acids) in CASP13 (2018) and generated the best 3D models for two of them among all the human and server groups including DeepMind\u0026#39;s AlphaFold. Inspired by our\u0026nbsp;success\u0026nbsp;in CASP12 in 2016, this deep learning technique has been adopted widely by the structure prediction community and thus, resulted in the widespread, largest progress in the history of CASP, which will also be discussed in this\u0026nbsp;talk.\u0026nbsp;\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EBio:\u0026nbsp;\u003C\/strong\u003EDr. Jinbo Xu is a full professor at the Toyota Technological Institute at Chicago, a computer science research and educational institute located at the University of Chicago. Dr. Xu\u0026rsquo;s research lies in machine learning, optimization, and computational biology. He has developed several popular bioinformatics programs such as the CASP-winning RaptorX (\u003Ca href=\u0022http:\/\/raptorx.uchicago.edu\/\u0022 target=\u0022_blank\u0022\u003Ehttp:\/\/raptorx.uchicago.edu\u003C\/a\u003E) for protein structure prediction and IsoRank\/HubRank for interaction network analysis. The deep learning method initiated by him for protein contact\/distance prediction has been widely adopted by the community and resulted in the largest progress in the history of protein structure prediction, due to which he was invited to give a keynote talk at the 2019 3DSIG session of ISMB, the largest bioinformatics conference in the world. Dr. Xu is an Associate Editor of the Bioinformatics journal and has received many awards, including Alfred P.

We employ a panel vector auto-regression (PVAR) model to investigate the inter-relationship between broadcasting promotions in social media and music sales, while controlling for influential factors such as album prices, advertising in traditional media channels, artist popularity, and the impact of user-generated content. We characterize two types of broadcast messages under the MySpace context, personal and automated. We find that broadcasting in social media has a significant effect on sales even after controlling for the aforementioned factors, and more importantly the effect mainly comes from personal messages rather than automated messages.

Matrices of these systems are becoming larger, more ill-conditioned, and are often poorly structured, and indefinite. Multilevel methods have been advocated for handling some of these challenges. This talk will introduce a variety of multilevel preconditioners for solving linear systems of equations, with an emphasis on indefinite systems. We begin with the Algebraic Recursive Multilevel Solver (ARMS) and see how a class of \u0022coarsening\u0022 schemes can be adapted to this framework.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EILU-type preconditioners have difficulties for some types of indefinite problems.

This highlights a growing need to develop technologies that enable rapid and accurate characterization of RNA structure.

These limitations thus pose a major barrier to comprehensive determination of structure from sequence.\u003C\/p\u003E\u003Cp\u003ETo address this need, we have developed a high-throughput structure characterization assay, called SHAPE-Seq, which simultaneously measures structural information at nucleotide-resolution for hundreds of distinct RNAs.

Following sequencing, we extract the structural information using a fully automated algorithmic pipeline that we developed. In this talk, I will focus on SHAPE-Seq\u0027s analysis methodology, which relies on a novel probabilistic model of a SHAPE-Seq experiment, adjoined by maximum-likelihood parameter estimation.

Thus, to make science-based predictions about sea-level rise, it is crucial that the ice sheets covering those land masses be accurately mathematically modeled and computationally simulated. In fact, the 2007 IPCC report on the state of the climate did not include predictions about sea level rise because it was concluded there that the science of ice sheets was not developed to a sufficient degree. As a result, such predictions could not be rationally and confidently made. In recent years, there has been much activity in trying to improve the state-of-the-art of ice sheet modeling and simulation. In this lecture, we review a hierarchy of mathematical models for the flow of ice, pointing out the relative merits and demerits of each, showing how they are coupled to other climate system components, and discussing where further modeling work is needed. We then discuss algorithmic approaches for the approximate solution of ice-sheet flow models and present and compare results obtained from simulations using the different mathematical models.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EMax Gunzburger is the Frances Eppes Eminent Professor and Founding Chair of the Department of Scientific Computing at Florida State University.

In this talk I will give an overview of some of this work. I will first spend some time motivating game theoretic treatment of problems relating to cyber and describe some important modeling considerations. In the remainder, I will describe two game theoretic models (one very briefly), and associated solution techniques and analyses. The first is the \u0022optimal attack plan interdiction\u0022 problem. In this model, we view a threat formally as a sophisticated planning agent, aiming to achieve a set of goals given some specific initial capabilities and considering a space of possible \u0022attack actions\/vectors\u0022 that may (or may not) be used towards the desired ends. The defender\u0027s goal in this setting is to \u0022interdict\u0022 a select subset of attack vectors by optimally choosing among miti-gation options, in order to prevent the attacker from being able to achieve its goals. I will describe the formal model, explain why it is challenging, and present highly scalable decomposition-based integer programming techniques that leverage extensive research into heuristic formal planning in AI. The second model addresses the problem that defense decisions are typically decentralized. I describe a model to study the impact of decentralization, and show that there is a \u0022sweet spot\u0022: for an intermediate number of decision makers, the joint decision is nearly socially optimal, and has the additional benefit of being robust to the changes in the environment.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EFinally, I will describe the Secure Design Competition (FIREAXE) that involved two teams of interns during the summer of 2012. The problem that the teams were tasked with was to design a highly stylized version of an electronic voting system. The catch was that after the design phase, each team would attempt to \u0022attack\u0022 the other\u0027s design. I will describe some salient aspects of the specification, as well as the outcome of this competition and lessons that we (the designers and the students) learned in the process.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EYevgeniy Vorobeychik\u003C\/strong\u003E\u0026nbsp;is a Principal Member of Technical Staff at Sandia National Laboratories.

They have many favorable properties such as excellent wear resistance and high tensile strength, but are prone to breakage in some circumstances, depending on their method of preparation. The talk will describe the development of a quasi-static projection method within an Eulerian finite-difference framework, for simulating a new physical model of a metallic glass. The simulations are capable of resolving the multiple timescales that are involved, and provide an explanation of the experimentally observed differences in breakage strength, which may aid in the use of these materials in practical applications. The same Eulerian simulation framework can be adapted to address a variety of other problems, such as fluid-structure interaction, and the mechanical modeling of multicellular clusters.\u003Cbr \/\u003E\u003Cbr \/\u003E\u003Cstrong\u003EBiography:\u003C\/strong\u003E\u003Cbr \/\u003EChris Rycroft is a Morrey Assistant Professor in the Departments of Mathematics at the University of California, Berkeley and the Lawrence Berkeley National Laboratory.

Two projects nicely fit into the usual mold of technique-driven work on algorithms for DR. Glimmer is a multilevel multidimensional scaling (MDS) algorithm that exploits the GPU. Glint is a new MDS framework that achieves high performance on costly distance functions. In contrast, the DimStiller project is a foray into systems rather than algorithms, built around the idea of \u0022DR for the rest of us\u0022. It is a toolkit for DR that provides local and global guidance to users who may not be experts in the mathematics of high-dimensional data analysis. A third kind of project combines evaluation and the creation of taxonomies. Our recent taxonomy of visual cluster separation factors arose from the systematic qualitative examination of over 800 scatterplots of dimensionally reduced data, and includes an analysis of the reasons for failure of previous cluster separation metrics. I will also discuss the current work of a task taxonomy that is grounded in a two-year qualitative study of high-dimensional data analysts in many domains, to discover how the use of DR \u0022in the wild\u0022 does and does not match up with the assumptions that underlie previous algorithmic work.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003ETamara Munzner is a professor at the University of British Columbia Department of Computer Science, where she has been since 2002.

The type of corruption is application-dependent and may be caused by measurement errors, or natural features of the phenomenon. We assume that an appropriate metric exists, which measures the amount of corruption experienced. We study the problem of recovering the corrupted cycle under various error models, formally called the period recovery problem. Specifically, we identify a metric property which we call pseudo-locality and study the period recovery problem under pseudo-local metrics. Examples of pseudo-local metrics are the Hamming distance, the swap distance, and the interchange (or Cayley) distance. We show that for pseudo-local metrics, periodicity is a powerful property allowing detecting the original cycle and correcting the data, under suitable conditions. Some surprising features of our algorithm are that we can efficiently identify the corrupted period, up to number of possibilities logarithmic in the length of the data string, even for metrics whose calculation is NP-hard. \u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EJoint work with Estrella Eisenberg, Avivit Levy, Ely Porat, and Natalie Shapira \u003C\/p\u003E\u003Cp\u003E~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\u0026nbsp;\u003C\/p\u003E\u003Cp\u003ETo receive future announcements, please sign up to the cse-seminar email list:\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022https:\/\/mailman.cc.gatech.edu\/mailman\/listinfo\/cse-seminar\u0022\u003Ehttps:\/\/mailman.cc.gatech.edu\/mailman\/listinfo\/cse-seminar\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Cycle Detection and Correction"}],"uid":"27439","created_gmt":"2011-08-31 13:10:52","changed_gmt":"2016-10-08 01:55:34","author":"Lometa Mitchell","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2011-09-09T15:00:00-04:00","event_time_end":"2011-09-09T16:30:00-04:00","event_time_end_last":"2011-09-09T16:30:00-04:00","gmt_time_start":"2011-09-09 19:00:00","gmt_time_end":"2011-09-09 20:30:00","gmt_time_end_last":"2011-09-09 20:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"37041","name":"Computational Science and Engineering"},{"id":"47223","name":"College of Computing"},{"id":"50877","name":"School of Computational Science and Engineering"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EFor more information please contact\u0026nbsp;Dr. Alberto Apostolico at \u003Ca href=\u0022mailto:axa@cc.gatech.edu\u0022\u003Eaxa@cc.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"65791":{"#nid":"65791","#data":{"type":"event","title":"CSE Seminar: Alexandar Smola","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EAlexander Smola\u003C\/strong\u003E\u003Cbr \/\u003EYahoo!

Many of them have rich microscopic structures where each variable can take values on manifolds (e.g., camera rotations), combinatorial objects (e.g., texts, graphs of drug compounds) or high dimensional continuous domains (e.g., images and videos). Furthermore, these problems may possess additional macroscopic structures where the large collections of observed and hidden variables are connected by networks of conditional independence relations (e.g., in predicting depth from still images, and forecasting in time-series).\u003C\/p\u003E\u003Cp\u003EMost previous learning algorithms for problems with such rich structures rely heavily on linear relations and parametric models where data are typically assumed to be multivariate Gaussian or discrete with a relatively small number of values.

The key idea of the method is to map distributions to their expected features (potentially infinite dimensional), and given evidence, update these new representations solely in the feature space. Compared to existing nonparametric representations which are largely restricted to vectorial data and usually lead to intractable algorithms, very often kernel distribution embeddings lead to simpler, faster and more accurate algorithms in a diverse range of problems such as organizing photo albums, understanding social networks, retrieving documents across languages, predicting depth from still images and forecasting sensor time-series.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003ELe Song is a post doctoral fellow at School of Computer Science, Carnegie Mellon University, working with a number of professors, including Eric Xing, Carlos Guestrin, Geoff Gordon and Jeff Schneider.

Key inputs, parameters, or structural aspects of models may be incomplete or unknown, and must be developed from indirect and limited observations. At the same time, quantified uncertainties are needed to qualify computational predictions in the support of design and decision-making. In this context, Bayesian statistics provides a foundation for inference and for the optimal selection of experiments and observations. Computationally intensive models, however, can render a Bayesian approach prohibitive.\u003C\/p\u003E\u003Cp\u003EWe will show that stochastic spectral methods, which have seen extensive development in the context of \u0022forward\u0022 uncertainty propagation, are a useful tool for inference as well. We introduce a stochastic spectral formulation that accelerates Bayesian inference via rapid exploration of a surrogate posterior distribution. Theoretical convergence results are verified with several numerical examples---in particular, parameter estimation in transport processes and in chemical kinetic systems. We also extend this approach to high-dimensional and ill-posed inverse problems, estimating distributed quantities in a hierarchical Bayesian setting.\u003C\/p\u003E\u003Cp\u003EWe will also discuss computational strategies for optimal experimental design---choosing experimental conditions to maximize information gain in parameters or outputs of interest. We propose a general Bayesian framework for experimental design with nonlinear simulation-based models, accounting for uncertainty in model parameters, experimental conditions, and observables. We then discuss efficient evaluation of the associated objective functions, coupled with stochastic optimization methods to maximize expected utility.\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022mailto:ymarz@mit.edu\u0022\u003Eymarz@mit.edu\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003E~~~~~~~~~~~~~~~~\u003C\/p\u003E\u003Cp\u003ETo receive future announcements, please sign up to the cse-seminar email list:\u003Cbr \/\u003E\u003Ca href=\u0022https:\/\/mailman.cc.gatech.edu\/mailman\/listinfo\/cse-seminar\u0022 title=\u0022https:\/\/mailman.cc.gatech.edu\/mailman\/listinfo\/cse-seminar\u0022\u003Ehttps:\/\/mailman.cc.gatech.edu\/mailman\/listinfo\/cse-seminar\u003C\/a\u003E\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Algorithms for inference and experimental design in complex physical systems"}],"uid":"27154","created_gmt":"2011-01-26 10:08:49","changed_gmt":"2016-10-08 01:53:56","author":"Louise Russo","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2011-01-28T13:00:00-05:00","event_time_end":"2011-01-28T14:00:00-05:00","event_time_end_last":"2011-01-28T14:00:00-05:00","gmt_time_start":"2011-01-28 18:00:00","gmt_time_end":"2011-01-28 19:00:00","gmt_time_end_last":"2011-01-28 19:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"37041","name":"Computational Science and Engineering"},{"id":"47223","name":"College of Computing"},{"id":"50877","name":"School of Computational Science and Engineering"}],"categories":[],"keywords":[{"id":"3497","name":"cse seminar"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EGeorge Biros\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022mailto:gbiros@cc.gatech.edu\u0022\u003Egbiros@cc.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"63423":{"#nid":"63423","#data":{"type":"event","title":"CSE Convocation","body":[{"value":"\u003Cp\u003EIn 2010 Georgia Tech announced the creation of the School of Computational Science and Engineering (CSE) within the College of Computing.

In many cases, we can reduce the total runtime significantly by taking into account how the problem changes and recycling judiciously selected results from previous computations.

This idea has gained popularity over the last decade in several areas of scientific computing, include numerical linear algebra, signal processing, and partial differential equations. The Sundance project is such an example, using high-level software-based differentiation of variational forms to automatically produce high-performance finite element implementations, all within a C++ library. In addition to automating the discretization of PDE by finite elements, recent work is demonstrating how to produce block-structured matrices and streamline the implementation of advanced numerical methods.

The problems we consider are (a) the classical statistical problem\nof unraveling a sample from a mixture of k unknown Gaussians and (b) the\nclassic learning theory problem of learning an intersection of k halfspaces.\nDuring the talk, we will encounter recent extensions of PCA that are\nnoise-resistant, affine-invariant and nonviolent.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"\u0022The Joy of PCA\u0022"}],"uid":"27174","created_gmt":"2010-09-15 13:31:50","changed_gmt":"2016-10-08 01:52:18","author":"Mike Terrazas","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2010-09-17T15:00:00-04:00","event_time_end":"2010-09-17T16:00:00-04:00","event_time_end_last":"2010-09-17T16:00:00-04:00","gmt_time_start":"2010-09-17 19:00:00","gmt_time_end":"2010-09-17 20:00:00","gmt_time_end_last":"2010-09-17 20:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"37041","name":"Computational Science and Engineering"},{"id":"47223","name":"College of Computing"},{"id":"50877","name":"School of Computational Science and Engineering"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EFor more information, contact \u003Ca href=\u0022mailto:lebanon@cc.gatech.edu\u0022\u003EGuy Lebanon\u003C\/a\u003E.\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"60773":{"#nid":"60773","#data":{"type":"event","title":"CSE Seminar: M.M.

Complexity is well handled by first-order logic, and uncertainty by probabilistic graphical models. Statistical relational learning seeks to combine the two. Markov logic networks (MLNs) do this by attaching weights to logical formulas and treating them as templates for features of Markov random fields. This talk will cover MLN representation, inference, learning and applications. MLN inference techniques are based on satisfiability testing, resolution, Markov chain Monte Carlo, and belief propagation. Learning techniques include pseudo-likelihood, voted perceptrons, second-order convex optimization, and inductive logic programming. MLNs have been applied in a wide variety of areas, including natural language processing, information extraction and integration, robot mapping, social networks, computational biology, and others. Open-source implementations of MLN algorithms are available in the Alchemy package (alchemy.cs.washington.edu).

In this talk, I will present our recent work on (1) querying (e.g., given a social network, how to measure the closeness between two persons? how to track it over time?); and (2) mining (e.g., how to identify abnormal behaviors of computer networks? In the case of virus attacks, which nodes are the best to immunize?) large graphs.\u003C\/p\u003E\u003Cp\u003EFor the task of querying, our main finding is that many complex user-specific patterns on large graphs can be answered by means of proximity measurement. In other words, proximity allows us to query large graphs on the atomic levels. Then, I will talk about how to adapt querying tasks to the time evolving graphs. For fast computation of proximity, we developed a family of fast solutions to compute the proximity in several different scenarios. By carefully leveraging some important properties shared by many real graphs (e.g., the block-wise structure, the linear correlation, the skewness of real bipartite graphs, etc), we can often achieve orders of magnitude of speedup with little or no quality loss. For the task of mining, I will talk about immunization and anomaly detection. For immunization, we proposed a near-optimal, fast and scalable algorithm. For anomaly detection, we proposed a family of example-based low-rank matrix approximation methods. The proposed algorithms are provably equal to or better than best known methods in both space and time, with the same accuracy.

We show that its information content, as measured by sub-extensive entropy, can grow as fast as\u0026nbsp; K log(N), which is faster than the usual 1\/2 K log(N) for exchangeable sequences generated by random posterior sampling from a Bayesian model. In continuous spaces we show that a kernel version of herding generates samples form a density that, when used to compute Monte Carlo sums, converges at a rate O(1\/T) (as opposed to O(1\/sqrt(T)) for random samples).

Analytic visualizations are distinguished from other graphics by their mathematical formalism. Informal diagrams, by contrast, are designed to communicate ideological, artistic, religious, or other metaphorical information. \u003C\/p\u003E\u003Cp\u003EThe GoG foundation is based on the conventional definition of the graph of a function: a collection of ordered pairs (x, f(x)). A graphic is a visual representation of the graph of a function. In analytic visualizations, this function operates on observed or abstract data. \u003C\/p\u003E\u003Cp\u003EGoG decomposes the global visualization function into seven orthogonal classes that comprise a totally ordered function chain. Each class has a collection of member functions that are composable with functions in adjacent classes of the function chain. The \ufb01rst class (Variables) maps data to an object called a varset (a set of variables). The next two classes (Algebra, Scales) are transformations on varsets. The next class (Statistics) takes a varset and creates a statistical graph (a statistical summary). The next class (Geometry) maps a statistical graph to a geometric graph. The next (Coordinates) embeds a graph in a coordinate space. And the last class (Aesthetics) maps a graph to a visible or perceivable display called a graphic. \u003C\/p\u003E\u003Cp\u003EA consequence of this class-orthogonality is a high degree of expressiveness: the product set of these seven function classes produces a huge variety of graphical forms or chart types. In fact, it is claimed that virtually the entire corpus of known statistical charts can be generated by this relatively parsimonious system, and perhaps a great number of meaningful but undiscovered chart types as well. \u003C\/p\u003E\u003Cp\u003EThe second principal claim of GoG is that this function chain encapsulates the meaning of what we do when we construct formal statistical graphics, charts, and visualizations. It is not a taxonomy. It is a computational system based on the underlying mathematics of \u003Cbr \/\u003Erepresenting functions of data. A consequence of this claim is to say that charts not definable within the GoG chain should be carefully examined for the possibility that they are ill-formed (meaningless).\u003C\/p\u003E\u003Cp\u003EThis talk will include concrete examples to illustrate distinguishing characteristics of visualization languages based on GoG: simplicity, expressiveness, coherence, and meaningfulness.

New radical algorithmic approaches are needed that emphasize minimization of data transmission instead of floating point performance.

For example, expression of a particular gene may cause resistance to an anticancer drug, but only over certain types of cancer cell-lines. It may not be known in advance which types of cancer cell-lines (e.g., estrogen-regulated, newly differentiated, central nervous system) employ such a method of resistance. This situation differs from the usual setting in which partial correlations are estimated conditional on a known selection, such as the value of another variable. For any pair of variables of interest, the goal is to test if these are associated in some unspecified subpopulation that is represented by a subsample of the data we have available.\u0026nbsp;\u0026nbsp; Previous approaches rely heavily on bivariate normal assumptions, which are not easily adapted to non-linear association. We have tried several parametric and non-parametric approaches, and for both inferential and computational reasons have chosen to present a procedure based on a sequential development of Kendall\u02bcs tau measure of monotone association. The sequence is achieved by reordering observations so that the sample tau coefficients {Tk} for the first k=2,...,n of the n observations form a monotone decreasing path, ending at Kendall\u02bcs tau coefficient Tn. Boundaries are constructed so that 95% of the paths remain within the boundaries under the null hypothesis of independence. A boundary crossing at any point k is evidence of a\\ stronger than expected association amongst a subpopulation represented by the k observations involved. The method is used to screen for association between gene expression and compound activity amongst types of cancer cell-lines in the NCI-60 database.\u003C\/p\u003E\u003Cp\u003EMore generally, the method may be used to deconvolve a mixture of absolutely continuous bivariate distributions with the same margins but differing in strength of association.\u0026nbsp;\u0026nbsp; We prove that a particular method of reordering the observations is optimal against any other ordering for simultaneously identifying the highest \u03c4 association in subsets of size k (k=2,...,n). Furthermore, assuming a subpopulation of k, we present a way of quantifying how likely any observation is to be in that subpopulation. Extensions of this basic method to conditional testing, survival data, and time-series are described briefly.\u003C\/p\u003E\u003Cp\u003EThis is joint work with Li Yu (MedImmune) and Paul Blower (Leadscope).\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EJoe graduated from MIT with an SB in Mathematics, completed his Ph.D. at Stanford in Statistics, and did post-doctoral work at Carnegie-Mellon before taking a permanent position in the Statistics Department at the Ohio State University.

Traditionally, a species tree is inferred by (1) sequencing a genomic region of interest from the group of species under study, (2) reconstructing its evolutionary history, and (3) declaring it to be the estimate of the species tree. However, recent analyses of increasingly available multi-locus data from various groups of organisms have demonstrated that different genomic regions may have evolutionary histories (called\u201cgene trees\u201d) that may disagree with each other, as well as with that of the species. This observation has called into question the suitability of the traditional approach to species tree inference. Further, when some, or all, of these disagreements are caused by reticulate evolutionary events, such as hybridization, then the phylogenetic relationship of the species is more appropriately modeled by a phylogenetic network than a tree. As a result, a new, post-genomic paradigm has emerged, in which multiple genomic regions are analyzed simultaneously, and their evolutionary histories are reconciled in order to infer the evolutionary history of the species, which may not necessarily be treelike.\u0026nbsp; In this talk, I will describe our recent work on developing mathematical criteria and algorithmic techniques for analyzing incongruence among gene trees, and inferring phylogenetic relationships among species despite such incongruence. This includes work on lineage sorting, reticulate evolution, as well as simultaneous treatment of both. If time permits, I will describe our recent work on population genomic analysis of bacterial data,and the implications on the evolutionary forces shaping the genomic diversity in these populations.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003ELuay Nakhleh is an Assistant Professor of Computer Science and Biochemistry and Cell Biology at Rice University, and an adjunct Assistant Professor of Systems Biology at MD Anderson Cancer Center.

Since these codes are typically based on low-order finite volume methods, high-order methods such as discontinuous Galerkin (DG) methods have been advocated as alternative discretization techniques. DG methods are weighted residual methods with discontinuous approximate solution spaces typically consisting of polynomials defined on each element of the geometry triangulation. The inter-element connectivities are enforced through a proper definition of numerical fluxes along the shared boundaries between elements. Like more traditional finite element methods (continuous Galerkin methods), DG methods are well-suited for simulations in complex geometries. Moreover, they offer advantages in capturing features of convection-dominated flows, facilitating hp-adaptivity, ease of parallelization, and in the effectiveness of block diagonal iterative solvers. For these advantages to be realized in industrial simulations, efficient solution strategies should be developed for systems arising from high-order DG discretizations. Addressing this issue in the context of solving both incompressible and compressible Navier-Stokes equations is the focus of this talk.\u003C\/p\u003E\u003Cp\u003EFor the unsteady incompressible Navier-Stokes equations, we present an efficient parallel solver based on high-order DG methods using triangular and tetrahedral meshes in two and three space dimensions, respectively. In the context of semi-explicit temporal discretization, we present an algorithm with compact stencil sizes for all discrete equations yielding minimum computation and communication costs.\u003C\/p\u003E\u003Cp\u003EFor the compressible Navier-Stokes equations, we present multigrid algorithms for systems arising from high-order DG discretizations on unstructured meshes. The algorithms are based on coupling both functional and geometric multigrid methods which are used in non-linear or linear forms, and either directly as solvers or as preconditioners to a Newton-Krylov method.\u003C\/p\u003E\u003Cp\u003EWe identify two areas that need further explorations, namely developing new high-order DG algorithms for high-speed flows involving strong shock discontinuities, and methods for efficient simulation of flow-structure interactions. Finally, we describe the motivation behind our current research effort on devising hybrid Fourier continuation-WENO finite difference solvers for simulating high-speed multi-material compressible flows such as Richtmyer-Meshkov instabilities.

Analysis of such massive data sets is typically I\/O-bound: many parallel analysis programs spend most of their execution time reading data from disk rather than performing useful computation. To overcome this I\/O bottleneck, we have developed a new data access method. Our main idea is to cache a copy of simulation output files on the local disks of an analysis cluster\u2019s compute nodes, and to use a novel task-assignment protocol to co-locate data access with computation. We have implemented our methodology in a parallel disk cache system called Zazen. By avoiding the overhead associated with querying metadata servers and by reading data in parallel from local disks, Zazen is able to deliver a sustained read bandwidth of over 20 gigabytes per second on a commodity Linux cluster with 100 nodes, approaching the optimal aggregated I\/O bandwidth attainable on these nodes. Compared with conventional NFS, PVFS2, and Hadoop\/HDFS, respectively, Zazen is 75, 18, and 6 times faster for accessing large (1-GB) files, and 25, 13, and 85 times faster for accessing small (2-MB) files. We have deployed Zazen in conjunction with Anton\u2014a special-purpose supercomputer that dramatically accelerates molecular dynamics (MD) simulations\u2014and have been able to accelerate the parallel analysis of terabyte-scale MD trajectories by about an order of magnitude.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003ETiankai Tu is a computer scientist at D.

This assumption is rather restrictive in many research applications.\u003C\/p\u003E\u003Cp\u003EIn the first part of this seminar, I will introduce a model-based method for clustering random functions which are spatially interdependent. The time functions are decomposed into spatial global and time-dependent cluster effects using a semi-parametric model.

We illustrate this correlation analysis within a demographic study, in which we analyze the association between per capita income and racial-ethnic diversity.\u003C\/p\u003E\u003Cp\u003EThis is joint work with Huijing Jiang, PhD student in ISyE, Georgia Institute of Technology\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003ENicoleta Serban is an assistant professor in ISyE.

Such a formulation covers nearly all statistical models that we have encountered: e.g., linear (regression) model or parametric models with g being linear or belonging to a specific parametric family; nonlinear models such as kernel methods, splines, local polynomials, etc., when g has a particular form. We consider a variation of the above by reconsidering the penalized estimation framework: finding f which optimize a function having form G(f) + R(f), where G(f) is called a goodness of fit measure and R(f) measures the regularity of the functional solution f. It is known that under certain circumstances, the solutions to the above has a close-form solutions: e.g., when G(f) is the residuals sum of squares and R(f) is the integrated square of the second derivative of f, the minimizer f is the finite-dimensional cubic smoothing splines. It is also known that the above does not have a direct generalization to high-dimensional X. On the other hand, the date with high-dimensional X is frequently encountered in practice. We introduce an alternative to R(f), which leads to close-form solution and easy numerical implementation. Experiments with both synthetic and real data demonstrate the superiority of our method. The resulting model is nonlinear, not covered by any existing family of models, and requires very little assumption on the underlying f. Potential theoretical results will be discussed. The newly introduced R(f) is motivated by the work of hessian eigenmaps -- a manifold-based dimension reduction algorithm.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EXiaoming Huo received the B.S. degree in mathematics from the University of Science and Technology, China, in 1993, and the M.S. degree in electrical engineering and the Ph.D. degree in statistics from Stanford University, Stanford, CA, in 1997 and 1999, respectively.

A typical Web search involves a series of operations based on the user\u0027s query, from automatic spelling correction and identifying common word variants to the actual document ranking. Such operations tend to have a risk-reward tradeoff depending on how they \u0022bet\u0022 on different solution hypotheses.

I discuss how casting query expansion as a \u003Cbr \/\u003Econstrained optimization problem over a word graph provides a selective, highly effective modeling framework that reduces the number and magnitude of expansion failures with no loss in the strong average-case gain of the underlying expansion algorithm.
