Stratified Learning: A General-Purpose Statistical Method for Improved Learning under Covariate Shift

no code implementations21 Jun 2021 Maximilian Autenrieth, David A. van Dyk, Roberto Trotta, David C. Stenning

We propose a simple, statistically principled, and theoretically justified method to improve supervised learning when the training set is not representative, a situation known as covariate shift.
