SUMMARY:TILOS-HDSI Seminar: A New Paradigm for Learning with Distribution Shift
DESCRIPTION:Adam Klivans\, The University of Texas at Austin \nAbstract: We revisit the fundamental problem of learning with distribution shift\, where a learner is given labeled samples from training distribution D\, unlabeled samples from test distribution D′ and is asked to output a classifier with low test error. The standard approach in this setting is to prove a generalization bound in terms of some notion of distance between D and D′. These distances\, however\, are difficult to compute\, and this has been the main stumbling block for efficient algorithm design over the last two decades. \nWe sidestep this issue and define a new model called TDS learning\, where a learner runs a test on the training set and is allowed to reject if this test detects distribution shift relative to a fixed output classifier. This approach leads to the first set of efficient algorithms for learning with distribution shift that do not take any assumptions on the test distribution. Finally\, we discuss how our techniques have recently been used to solve longstanding problems in supervised learning with contamination. \n\nAdam Klivans is a Professor of Computer Science at the University of Texas at Austin and Director of the NSF AI Institute for Foundations of Machine Learning (IFML). His research interests lie in machine learning and theoretical computer science\, in particular\, Learning Theory\, Computational Complexity\, Pseudorandomness\, Limit Theorems\, and Gaussian Space. Dr. Klivans is a recipient of the NSF CAREER Award and serves on the editorial board for the Theory of Computing and Machine Learning Journal.
