Introduction

This repository contains a pytorch implementation of Style-Agnostic Networks (SagNets) for Domain Generalization. It is also an extension of our method which won the first place in Semi-Supervised Domain Adaptation of Visual Domain Adaptation (VisDA)-2019 Challenge. Details are described in Reducing Domain Gap by Reducing Style Bias, CVPR 2021 (Oral).
