Yann LeCun (@ylecun) 转发了 Alexi Gladstone (@AlexiGlad) 的帖子：
Progress in AI is driven by approaches that make weaker assumptions, which allows for better scaling
But representation learning has relied on strong assumptions like augmentations, masking, cropping, etc... until now!
🎬 Introducing Temporal Difference in Vision (TDV), a new paradigm for representation learning built on a single assumption: causality
TL;DR:
- We introduce TDV, the first approach to learn good representations without any augmentations, masking, cropping, or pixel-based reconstruction
- TDV matches SOTA recipes like DINO and iBOT on dense spatial tasks
- We show that as data scales, weaker assumptions work better
