Researchers have developed DSReg (Dependency-Sparsity Regularization), a novel method for recovering individual latent variables from world models without relying on reconstruction or auxiliary supervision. This approach leverages the concept of Structural Diversity, where different latent variables leave distinct dependency footprints on observations. DSReg can be applied post hoc to existing linearly identified representations, such as those from LeJEPA, and establishes the first fully identifiable JEPA capable of recovering every world latent. The method has demonstrated effectiveness across various synthetic and real-world scenarios, preserving dense prediction while enhancing individual-latent recovery and downstream utility. AI
