Slot-JEPA: Object-Structured Prediction Interfaces for Latent World Models

arXiv 2026 25.2 method

TLDR

Slot-JEPA decomposes JEPA latent representations into semantic slots and spatial masks, enabling a Transition Memory Predictor with UOT supervision for reusable object-structured world model prediction.

Reasoning

The paper offers a well-motivated architectural contribution that addresses object structure, temporal correspondence, and displacement sensitivity in latent world models. However, the abstract provides no empirical validation or real-world evaluation, so its effectiveness relative to existing methods remains unsupported.
