KAIST's Future-Aware Recall teaches world models which episodic memories to trust
kaist-ai · hf · 2026-10-02
KAIST AI proposes Future-Aware Recall (FAR), tackling the core episodic-memory problem for world models: as memory accumulates, which memories matter for the current prediction, and which retrieval cues should be trusted?
- Fixed criteria based on recency, pose overlap, or visual similarity are unreliable across environments and queries;
- FAR measures a memory's predictive utility via the conditional log-likelihood of the realized future given the recalled context (approximated by negative diffusion prediction loss) and trains a retriever that stays future-blind at inference;
- The retriever learns cue-specific relevance, automatically deciding when to trust time, pose, vision, or audio cues per query;
- Across three complementary settings, FAR beats hand-designed recall even with the same cues and recalls the right history as the world changes.
