SplitJEPA: Learning Invariant and Variant Latent Worlds without Reconstruction

SplitJEPA is introduced, a JEPA that jointly recovers the latent state and its invariant and variant organization directly in representation space, without any reconstruction, and extends reconstruction-free latent recovery to invariant-variant block identification.

DSReg: Provably Recovering Individual World Latents without Reconstruction

DSReg (Dependency-Sparsity Regularization) recovers individual world latents up to signed permutation, without reconstruction or a decoder, without reconstruction or a decoder, and establishes the first fully identifiable JEPA that recovers every world latent.

Towards Identifiable Representations under Misspecified Structure

This work characterize structural misspecification as a perturbed factor analysis problem, and establishes subspace identifiability under spectral separation and controlled perturbation, followed by component-wise identifiability under structural sparsity.

Hessian Rank Constraint for Learning Structure of Nonlinear Latent Variable Models

A condition called the cross-Hessian Rank Constraint (HRC), which serves as a primitive rank-based tool for nonlinear latent causal discovery, shows that a rank-based property arises from the cross-Hessian of the observed-data log-density in the nonlinear case, revealing information about the latent variables.

Requential Coding: Pushing the Limits of Model Compression with Self-Generated Training Data

Compression is fundamental to intelligence. A model that can represent its training data as a short code has discovered regularities that enable generalization. Large neural networks may learn functions far simpler than their parameter counts suggest, but it is challenging to construct codes that realize this simplicit...
