Attention Diversification for Domain Generalization

This repo is the official implementation of ECCV2022 paper "Attention Diversification for Domain Generalization".

Introduction

The pipeline of our proposed Attention Diversification framework is composed of Intra-Model Attention Diversification Regularization (Intra-ADR) and Inter-Model Attention Diversification Regularization (Inter-ADR). Intra-ADR is utilized to coaesely recall task-related features as much as possible, and then Inter-ADR is exploited to delicately distinguish domain- and task-related features for further suppression and enhancement respectively.

This code is based on Dassl.pytorch, the Intra-ADR and I2-ADR module are easily to implement, and the two modules' code can be found in ./dassl/engine/intra_adr.py and ./dassl/engine/i2_adr.py respectively.
