Title: Self-Supervised Learning from Images and Videos using Optimal Transport

Abstract:
In this talk we will learn more about self-supervised learning -- the principles, the methods and how properly utilizing video data will unlock unprecendented visual performances.
I will first provide a brief overview of self-supervised learning and show how clustering can be combined with representation learning using optimal transport ([1] @ ICLR'20 spotlight). Next, I will show how this method can be generalised to multiple modalities ([2] @NeurIPS'20) and for unsupervised segmentation in images ([3] @CVPR'22) and in videos ([4] @ICCV'23). Finally, I show how optimal transport can be utilized to learn models from scratch from just a single Walking Tour video that outperform those trained on ImageNet, demonstrating high potential for future video-based embodied learning ([5] @ICLR'24).
