Abstract: Time series learning has become a central problem in modern machine learning, with applications spanning science, engineering, healthcare, and finance. While much of the existing research has focused on improving forecasting accuracy, accurate prediction is only the starting point. This talk explores a broader view of time series learning, moving from forecasting toward reasoning and scientific discovery. I will first discuss our work on efficient time series forecasting, introducing cross-architecture knowledge distillation to develop lightweight models that achieve strong predictive performance with reduced computational costs. I will then explore spatio-temporal reasoning, presenting methods that integrate time series, spatial structures, and large language models to understand how events evolve and propagate across connected systems. Finally, I will discuss whether AI can move beyond prediction to discover the underlying mathematical and causal relationships governing temporal dynamics. These directions highlight the potential of time series learning to advance from accurate prediction toward deeper understanding and scientific discovery.

Abstract: We prove an Q(L/T) lower bound for first-order optimization of convex functions smooth relative to negative entropy on the simplex, showing mirror descent is nearly optimal and acceleration is generally impossible.
Unlike prior results, our prox-function is standard rather than pathological.
We extend the same non-acceleration result to quantum optimization over spectrahedra.
Abstract: Abstract: Decision-making under uncertainties has been a subject of study for many years. In particular, the decision making (optimization) for complex systems such as engineering and economic systems involves human-decision phase. This triggers the occurrences of uncertainties in the decision making phase in addition to the widely-existed inherent uncertainties in the actual systems. In this talk, such challenges will be addressed by summarizing the year’s efforts of the presenter when he was with the University of Manchester before 2016. At first, a generic framework on the decision making for uncertainty systems has been formulated into a “closed loop control design problem”, where the uncertainties in both decision making phase and the actual systems have been represented by the uncertainty injections to the “controller” and to the “plant to be controlled”. The uncertainties in human decision making phase is characterized by their probability density functions (PDF) of the brain-cell’s signal collected via brain-computer-interface (BCI). Using such a generic framework, decision making under uncertainties are formulated as a PDF control problem of objective functions and constraints- leading to a total solution for the stochastic optimization for complex systems. Two case studies will be presented together with the rationale and claims that most of the existing stochastic optimizations are special cases of the presented theory. Note that the presentation is based upon the published materials by the author.

Abstract: We study a class of nonconvex–nonconcave minimax problems in which the inner maximization problem satisfies a local Kurdyka–Łojasiewicz (KL) condition that may vary with the outer minimization variable. In contrast to the global KL or PL conditions commonly assumed in the literature—which are significantly stronger and often too restrictive in practice—this local KL condition accommodates a broader range of practical scenarios. However, it also introduces new analytical challenges. In particular, as an optimization algorithm approaches a stationary point, the region over which the KL condition holds may shrink, leading to a more intricate and potentially ill-conditioned landscape. To address this challenge, we show that the associated maximal function is locally generalized Hölder smooth. Leveraging this key property, we develop an inexact proximal gradient method for solving the minimax problem, where the inexact gradient of the maximal function is computed by applying a proximal gradient or sequential convex programming method to a KL-structured subproblem. Under mild assumptions, we establish complexity guarantees for computing an approximate stationary point of the minimax problem.

Abstract: Quantum systems introduce fundamentally new principles for computing, sensing, and applications in materials and chemistry. A defining distinction between quantum systems and their classical counterparts is the presence of entanglement, particularly multipartite entanglement involving many particles. The rapidly developing field of quantum materials therefore calls for increasingly precise metrological approaches to characterize and ultimately control such entanglement. While foundational advances, including Bell tests and many-body interferometry, were first established in quantum optics and few-body quantum simulators, extending these concepts to complex many-body states at the scale of materials remains a major challenge.
In this talk, I will introduce the entanglement-witness framework as a practical route for characterizing entanglement through experimentally accessible macroscopic observables in solid-state materials. This framework generalizes the underlying logic of Bell tests to macroscopic many-body systems. Recent advances include the detection of spin entanglement in quantum magnets using neutron scattering and spin-orbital entanglement using resonant inelastic X-ray scattering. I will then move beyond distinguishable local degrees of freedom and consider entanglement among indistinguishable fermions. This motivates a more general framework for multipartite electronic entanglement based on the cumulant reduced density matrix and nonlinear spectroscopic responses.

Abstract: Two-sided matching platforms, including labor markets, dating apps, accommodation services, and ridesharing systems, must make matching decisions in the presence of choice congestion and strategic platform design challenges. When agents have correlated preferences, popular options can attract too much demand, reduce overall efficiency, and lead to poor market outcomes. In this talk, I will present a framework for two-sided assortment optimization that studies how a platform should decide which options to display to agents and in what order, with the goal of improving matching performance. The main focus will be on maximizing the expected number of matches under general choice models. I will describe several natural classes of platform policies, ranging from static simultaneous displays to fully adaptive sequential policies, and compare their power through adaptivity gap results. I will also discuss polynomial-time approximation algorithms for computing near-optimal policies, and then briefly discuss the revenue-maximization version of the problem, where matches generate pair-dependent rewards. This talk is based on joint works with Alfredo Torrico, Ulysse Hennebelle, and Mohammadreza Ahmadnejadsaein.

Abstract: Recent advances in neuroimaging have produced massive and heterogeneous datasets, ranging from fMRI with high spatial resolution to EEG with high temporal resolution, characterized by complex spatiotemporal correlations and substantial inter-subject variability. Traditional regression models and Gaussian process (GP) approaches with fixed parametric kernels often fail to model such complex data effectively while maintaining scalability and interpretability. This talk introduces a family of modern Bayesian GP frameworks that integrate deep kernel learning, neural network priors, and geometric modeling for large-scale neuroimaging analysis. An example is the Deep Kernel Learning Process (DKLP), which embeds deep neural networks within GP priors to learn data-adaptive covariance structures directly from imaging data. DKLP provides a unified modeling foundation for image-on-scalar, scalar-on-image, and image-on-image regression, supported by theoretical guarantees and efficient posterior computation. Applications to fMRI data from the Adolescent Brain Cognitive Development (ABCD) study reveal reproducible cortical activation patterns associated with cognitive ability, while analyses of EEG-based brain–computer interface data demonstrate robust neural decoding under high noise. I will also discuss scalable heat-kernel GPs on manifolds and thresholded GP–based spatially varying neural network priors, which together expand the scope of Bayesian inference for complex neuroimaging data.

Abstract: Modern manufacturing generates increasingly rich in-situ sensing data, creating new opportunities for AI to enable automated and intelligent quality control decisions. However, conventional quality control using supervised learning relies on abundant labeled data and assumes that future product defects or process faults resemble those known during training. In practice, new defect types emerge, while abnormal conditions may be rarely observed or completely unknown. These challenges are particularly important for in-situ quality control, where defects must be detected or correctly classified for real-time decision-making, including newly emerging defects with limited or unavailable labels. Moreover, for latent defects that cannot be directly inspected online, defects must instead be predicted from indirect process-sensing signals. This requires mapping process-signal changes to possible defects despite scarce or unavailable defect training samples. This talk explores how advances in AI can address these challenges and enable more adaptive and intelligent in-situ quality control and decision-making for smart manufacturing.

Abstract: Many of today's most important applications rely on high-performance manipulation of matrices, tensors, and general arrays of data. The neural networks at the heart of AI language models are a prime example. The AI software stack relies on kernels (e.g., for matrix-matrix product) that are specifically designed to deliver throughput close to the hardware's theoretical peak. However, writing kernels that can deliver maximum performance is extremely challenging. In this talk, I will discuss some of the work we have done to simplify the task of authoring such kernels. This includes new abstractions to allow for algebraic manipulation of array layouts and new programming models for more easily expressing the kernels themselves.

]]>Abstract: Quantum computing promises to transform how we solve optimization problems—but currently available Noisy Intermediate Scale Quantum (NISQ era) devices alone cannot get us there. A promising path forward lies in hybrid approaches that combine the strengths of classical algorithms with the emerging capabilities of quantum hardware, opening the door to scalable and high-performance solutions. In this talk, I will present recent advances in quantum optimization that bring this vision to life. I will discuss how warm-starting the Quantum Approximate Optimization Algorithm (QAOA) with classical relaxations can dramatically improve performance, how hybrid pipelines leverage combinatorial structure to achieve stronger approximations and noise resilience, and how benchmark families—such as strongly regular graphs and low-degree graphs—help us probe the boundary of quantum advantage. These results connect classical approximation algorithms, convex optimization, and quantum circuit design. Looking ahead, I will outline a research vision for hybrid intelligence, where classical and quantum algorithms operate in synergy rather than competition—rethinking optimization for the next era of computing.

Abstract: In this talk, we discuss possible paths toward demonstrating quantum advantage in optimization, focusing primarily on quantum approximate multi-objective optimization. Multi-objective optimization seeks to understand optimal trade-offs between competing objectives by identifying sets of solutions that balance these trade-offs, a task that can be challenging for classical methods. This makes it a natural candidate for exploring potential benefits of quantum computing. We present a quantum algorithm for approximating such trade-offs in combinatorial optimization problems and illustrate its performance using both experiments on IBM quantum hardware and classical simulations. We conclude by discussing complementary paths toward quantum advantage in optimization, highlighting the role of systematic benchmarking efforts such as the Quantum Optimization Benchmarking Library (QOBLIB).

Abstract: The problem of discriminating among non-orthogonal quantum states arises throughout quantum information processing. For example, in quantum communications, a message is encoded as a quantum state and transmitted over a quantum channel to a receiver that decodes the message. In quantum sensing, a photon in a known state is emitted to gather information about the environment from its reflections. Underlying state discrimination are the design of the quantum measurement device used for measurement and the design of the hypotheses used to encode information or probe the environment. These are the core degrees of freedom in quantum information processing system design. This talk will present the design of three quantum detection tasks, including quantum state and channel discrimination over uncertain channels, sequential unambiguous quantum state and channel discrimination, and quickest quantum change-point detection. These designs make use of a range of classical non-convex optimization methods, including stochastic, bi-level, and multi-objective optimization.

Abstract: It is an exciting time for quantum science and technology research. While the promise of quantum computers continues to motivate billions of dollars of investment by the U.S. government and private sector, quantum sensors have already revolutionized aspects of our daily life. Established technologies like atomic clocks in space underlie GPS and nearly all communication systems that rely on precise time and frequency synchronization. Related technologies like magnetometers are opening up new research frontiers in biomagnetism. At the same time, there remains a cutting edge achieved in research labs but not yet fielded. In this talk, Robert will give a brief overview of quantum sensors and some of their applications. He will discuss the broad topic of magnetic imaging, and the numerous applications that fall within that category. Throughout the talk, he will highlight the interplay between sensor development and signal processing.
Abstract: Prior literature shows that self-reports, especially those of sensitive behaviors, tend to be biased. For example, respondents may over-report their family origin and volunteering experiences while under-reporting their drinking and smoking behaviors. In this study I examine a social network-based approach to addressing self-reporting bias, which is to ask peers (e.g. classmates or co-workers) to provide alternative reports that can be used to cross-validate and supplement self-reports. I first formalize the data generation process statistically by proposing a model containing two sub-models, one for the self-reports and the other for the peer-reports. In each of the sub-models, I treat the observed report as a probabilistic realization of a truthful report and a false report. The model can incorporate both self- and peer-characteristics and also dyadic characteristics. A Bayesian approach helps make the model self-containing by imposing a prior on the unknown ego's behavior. Then the Bayesian approach simulates self- and peer-reports according to the data generation process iteratively until the simulated reports emulate the observed reports. Through a case study on self- and peer-reports of smoking among adolescents, I demonstrate that the Bayesian approach can not only reveal how multiple characteristics are related to reporting biases but also incorporate these characteristics effectively into the imputation of the true behavior.

Abstract: The agriculture sector is a major economic driver for Africa. However, climatic change is driving severe disruption across Africa, causing prolonged dry seasons and erratic rainfall. As a result, farmers are facing lower farming yield. To mitigate this serious challenge, farmers must adopt modern and green technologies, like solar irrigation. To show the potential of solar irrigation system to mitigate this critical problem, a research project has been developed with the collaboration of Georgia Tech, University of Rwanda and Adama Science and Technology University. The project aims at developing a PV irrigation system that integrates IoT and controllers for real-time monitoring of the performance of the PV-irrigation system and for optimizing water conservation. This project is envisioned to be a prototype model for further scaling up the deployment of PV-irrigation systems in Africa to enhance sustainable agricultural.
As part of the whole project, this seminar focuses more on the design and economic assessment of the system for a particular village in Rwanda.

Abstract: Digital twins promise continuous, high-fidelity representations of physical systems, yet their practical deployment is often constrained by the computational cost of simulation and calibration. This talk presents a unified perspective on making digital twin calibration more efficient, adaptive, and scalable by learning where computational effort matters most.
The first part addresses offline calibration of block-structured models. I introduce a doubly importance-driven calibration method that learns which parameter blocks and which observations are most informative, and directs simulation effort toward the parts of the problem that contribute most to the optimization. This targeted allocation substantially reduces computational cost while preserving calibration accuracy.
The second part turns to online calibration, where model parameters evolve over time and computational resources are limited. The proposed framework combines fast, edge-side surrogate filtering with periodic, cloud-side discrepancy correction based on high-fidelity simulations. This two-tier architecture enables real-time parameter adaptation while maintaining consistency with the underlying digital twin.
Together, these methods show how learning what matters—in parameters, observations, and computation—can support digital twins that remain accurate, scalable, and continuously adaptive in practice.
