Test-Time Training for Generalization under Distribution Shifts

no code implementations ICML 2020 Yu Sun, Xiaolong Wang, Zhuang Liu, John Miller, Alexei Efros, University of California Moritz Hardt

We introduce a general approach, called test-time training, for improving the performance of predictive models when training and test data come from different distributions.

The Hessian Penalty: A Weak Prior for Unsupervised Disentanglement

1 code implementation ECCV 2020 William Peebles, John Peebles, Jun-Yan Zhu, Alexei Efros, Antonio Torralba

In this paper, we propose the Hessian Penalty, a simple regularization term that encourages the Hessian of a generative model with respect to its input to be diagonal.
