Untangle Generalization Errors for Better Test-Time Adaptation in Overparameterized Linear Regression.

Test-time adaptation (TTA) is a strategy that leverages unlabeled test data to adjust a pretrained model, improving robustness against distribution shifts. Recent advances in this research area are mostly driven by heuristic or empirical approaches with limited theoretical guidance. In particular, there is little theor...
