A Large-Scale Study on Unsupervised Spatiotemporal Representation Learning [PDF]
Computer Vision and Pattern Recognition, 2021 We present a large-scale study on unsupervised spatiotemporal representation learning from videos. With a unified perspective on four recent image-based frameworks, we study a simple objective that can easily generalize all these methods to space-time ...

Unsupervised Prompt Learning for Vision-Language Models [PDF]
arXiv.org, 2022 Contrastive vision-language models like CLIP have shown great progress in transfer learning. In the inference stage, the proper text description, also known as prompt, needs to be carefully designed to correctly classify the given images.
