Filtering, Distillation, and Hard Negatives for Vision-Language Pre-Training

CVPR 2023poster

Vision-language models trained with contrastive learning on large-scale noisy data are becoming increasingly popular for zero-shot recognition problems. In this paper we improve the following three aspects of the contrastive pre-training pipeline: dataset noise, model initialization and the training…

Making Heads or Tails: Towards Semantically Consistent Visual Counterfactuals

ECCV 2022poster

"A visual counterfactual explanation replaces image regions in a query image with regions from a distractor image such that the system’s decision on the transformed image changes to the distractor class. In this work, we present a novel framework for computing visual counterfactual explanations base…

Revisiting Contrastive Methods for Unsupervised Learning of Visual Representations

NeurIPS 2021poster

Contrastive self-supervised learning has outperformed supervised pretraining on many downstream tasks like segmentation and object detection. However, current methods are still primarily applied to curated datasets like ImageNet. In this paper, we first study how biases in the dataset affect existin…

Unsupervised Semantic Segmentation by Contrasting Object Mask Proposals

ICCV 2021poster

Being able to learn dense semantic representations of images without supervision is an important problem in computer vision. However, despite its significance, this problem remains rather unexplored, with a few exceptions that considered unsupervised semantic segmentation on small-scale datasets wit…

MTI-Net: Multi-Scale Task Interaction Networks for Multi-Task Learning

ECCV 2020poster

In this paper, we argue about the importance of considering task interactions at multiple scales when distilling task information in a multi-task learning setup. In contrast to common belief, we show that tasks with high affinity at a certain scale are not guaranteed to retain this behaviour at othe…

SCAN: Learning to Classify Images without Labels

ECCV 2020poster

Can we automatically group images into semantically meaningful clusters when ground-truth annotations are absent? The task of unsupervised image classification remains an important, and open challenge in computer vision. Several recent approaches have tried to tackle this problem in an end-to-end fa…
