Uncertainty-guided Model Generalization to Unseen Domains (CVPR 2021)

This repository holds the Pytorch implementation of Uncertainty-guided Model Generalization to Unseen Domains by Fengchun Qiao and Xi Peng.

Introduction

We study a worst-case scenario in generalization: Out-of-domain generalization from a single source. The goal is to learn a robust model from a single source and expect it to generalize over many unknown distributions. This challenging problem has been seldom investigated while existing solutions suffer from various limitations. In this paper, we propose a new solution. The key idea is to augment the source capacity in both input and label spaces, while the augmentation is guided by uncertainty assessment.
