Optimal Ridge Regularization for Out-of-Distribution Prediction

Pratik Patil, Jin-Hong Du, Ryan J. Tibshirani

We study the behavior of optimal ridge regularization and optimal ridge risk for out-of-distribution prediction, where the test distribution deviates arbitrarily from the train dis…

Failures and Successes of Cross-Validation for Early-Stopped Gradient Descent

Pratik Patil, Yuchen Wu, Ryan J. Tibshirani

We analyze the statistical properties of generalized cross-validation (GCV) and leave-one-out cross-validation (LOOCV) applied to early-stopped gradient descent (GD) in high-dimens…
