Improving Out-of-Distribution Robustness via Selective Augmentation

Yao, Huaxiu, Wang, Yu, Li, Sai et al.

Understand

Machine learning algorithms typically assume that training and test examples are drawn from the same distribution.

  • However, distribution shift is a common problem in real-world applications and can cause models to perform dramatically worse at test time.
  • In this paper, we specifically consider the problems of subpopulation shifts (e.g., imbalanced data) and domain shifts.
  • While prior works often seek to explicitly regularize internal representations or predictors of the model to be domain invariant, we instead aim to learn invariant predictors without restricting the model's internal representations or predictors.
