• Our new arXiv paper "Decoupled Kullback-Leibler (DKL) Divergence Loss" achieves new state-of-the-art on adversarial robustness. Code is released.

Learnable Boundary Guided Adversarial Training

This repository contains the implementation code for the ICCV2021 paper:
Learnable Boundary Guided Adversarial Training (https://arxiv.org/pdf/2011.11164.pdf)

Updates: Training with Epsilon 8/255 on CIFAR-100

Overview

In this paper, we proposed the "Learnable Boundary Guided Adversarial Training" to preserve high natural accuracy while enjoy strong robustness for deep models. An interesting phenomenon in our exploration shows that natural classifier boundary can benefit model robustness to some degree, which is different from the previous work that the improved robustness is at cost of performance degradation on natural data. Our method creates new state-of-the-art model robustness on CIFAR-100 without extra real or Synthetic data under auto-attack benchmark.

Results and Pretrained models

`
Models are evaluated under the strongest AutoAttack(https://github.com/fra31/auto-attack) with epsilon 0.031.

CIFAR-100-LBGAT6-wideresnet-34-20 62.55 vs 30.20

Our CIFAR-10 models:
CIFAR-10-LBGAT0-wideresnet-34-10 88.22 vs 52.86
CIFAR-10-LBGAT0-wideresnet-34-20 88.70 vs 53.57
