LeJEPA already identified the world's latents--up to some mixing. There is now a very simple post-training recipe to undo that ambiguity and to recover the disentangled world's features! What a time to be Gaussian :)

Is it possible to provably recover individual latent variables of the true world, even without reconstruction (e.g., JEPA)?
Yes, with DSReg, a simple regularization that can be applied post hoc to your pretrained model!
