Revisiting Outer Optimization in Adversarial Training

ECCV 2022poster

"Despite the fundamental distinction between adversarial and natural training (AT and NT), AT methods generally adopt momentum SGD (MSGD) for the outer optimization. This paper aims to analyze this choice by investigating the overlooked role of outer optimization in AT. Our exploratory evaluations r…

Self-Supervised Wasserstein Pseudo-Labeling for Semi-Supervised Image Classification

CVPR 2021poster

The goal is to use Wasserstein metric to provide pseudo labels for the unlabeled images to train a Convolutional Neural Networks (CNN) in a Semi-Supervised Learning (SSL) manner for the classification task. The basic premise in our method is that the discrepancy between two discrete empirical measur…

SuperMix: Supervising the Mixing Data Augmentation

CVPR 2021poster

This paper presents a supervised mixing augmentation method termed SuperMix, which exploits the salient regions within input images to construct mixed training samples. SuperMix is designed to obtain mixed images rich in visual features and complying with realistic image priors. To enhance the effic…

Exploiting Joint Robustness to Adversarial Perturbations

CVPR 2020poster

Recently, ensemble models have demonstrated empirical capabilities to alleviate the adversarial vulnerability. In this paper, we exploit first-order interactions within ensembles to formalize a reliable and practical defense. We introduce a scenario of interactions that certifiably improves the robu…

Transporting Labels via Hierarchical Optimal Transport for Semi-Supervised Learning

ECCV 2020poster

Semi-Supervised Learning (SSL) based on Convolutional Neural Networks (CNNs) have recently been proven as powerful tools for standard tasks such as image classification when there is not a sufficient amount of labeled data available during the training. In this work, we consider the general setting…

Unsupervised Image-to-Image Translation Using Domain-Specific Variational Information Bound

NeurIPS 2018poster

Unsupervised image-to-image translation is a class of computer vision problems which aims at modeling conditional distribution of images in the target domain, given a set of unpaired images in the source and target domains. An image in the source domain might have multiple representations in the tar…
