Contrastive learning: teaching models by pulling likes together and pushing unlikes apart Lesson
Contrastive learning is a self-supervised training method that learns useful representations without labels by pulling matching pairs closer together in an embedding space and pushing mismatched pairs apart - the technique behind SimCLR and CLIP, and the classic alternative to generation-based approaches for teaching a model to perceive.
A video generator, repurposed as a perception model, matches specialists with up to 500x less data News
GenCeption repurposes a pre-trained video generative diffusion model as a feed-forward perception system, matching specialist vision models on depth, surface normals, pose and segmentation while using 7x to 500x less training data - and generalizing from synthetic-only training to real footage.
