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…

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…

A Weakly Supervised Fine Label Classifier Enhanced by Coarse Supervision

ICCV 2019poster

Objects are usually organized in a hierarchical structure in which each coarse category (e.g., big cat) corresponds to a superclass of several fine categories (e.g., cheetah, leopard). The objects grouped within the same coarse category, but in different fine categories, usually share a set of globa…
