Learning to Forget -- Hierarchical Episodic Memory for Lifelong Robot Deployment
H²-EMV lets robots incrementally build hierarchical episodic memory, selectively forget using LM-based rules learned from user feedback, cutting memory size 45% and query compute 35% while boosting follow-up query accuracy 70% over time.
