tl;dr

VICReg trains image-understanding models using pairs of similar images instead of human labels, so you need far less labeled data to build a working classifier.

how do i run it?

Difficulty · hard time til it works · 1h+

Training from scratch needs GPU infrastructure and can scale to multi-node clusters, though pretrained models are available to skip that step.
