Directed Exploration and Episodic Memory: ASRA Phase 3 — From Structure to Navigation
Phase 3 extends ASRA with the Navigation and Memory Engine: exploration graphs, visitation memory, novelty versus usefulness scoring, compositional subgoals, strategy reuse, and transition replay—building on Phase 1 transitions and Phase 2 object-centric observation. The article presents theory and architecture; a companion Kaggle notebook deploys compact exploration hints for ARC Prize 2026.
