H-JEPA Follow-Up: SIGReg Keeps Latent Spaces Well-Conditioned Across All Levels
randall_balestr · x · 2026-10-06
A follow-up on H-JEPA training details: end-to-end training of a hierarchical JEPA risks dimensional collapse, so the team leverages SIGReg to keep latent spaces well-conditioned across all levels without complicated heuristics — stable and easy to debug. Details overlap with the main thread post.
