Title:

Active Hypothesis Testing for Information Acquisition and Active Learning

Abstract:

In the first part of the talk, I will discuss an overview of my research on information acquisition and active learning in the context of the mission of our newly formed UCSD Center for Machine-Integrated Computing and Security (MICS). I will report of ongoing research on characterizing rate-reliability trade-off in active hypothesis testing, and hence bringing action into information theory and  Machine Learning. In the second part of the talk, I will delve deeper into  the problems of information acquisition, controlled sensing, and active learning and show our solutions to significantly reduce the cost of data collection and/or data labeling while ensuring reliability and fidelity during the training or run-time. In particular, we illustrate our findings and algorithms in the context of DetecDrone: an ML-enabled drone intelligence platform developed in my lab to provide search, mapping, and monitoring on off-the-shelf low cost drones.
