In many modern uses of predictive methods, there can be shifts between the distributional properties of training data compared to the test data. Such mismatches can cause dramatic reductions in accuracy that remain mysterious. How to find practical procedures that mitigate such effects in an optimal way? In this talk, we discuss the fundamental limits of problems with covariate shift, and simple procedures that achieve these fundamental limits. Our talk covers both the challenges of covariate shift in non-parametric regression, and also for semi-parametric problems that arise from causal inference and off-policy evaluation.

Based on joint works with: Peter Bartlett, Peng Ding, Cong Ma, Wenlong

Mou, Reese Pathak and Lin Xiao.
