[1] Beyond Fact Retrieval: Episodic Memory for RAG with Generative Semantic Workspaces
AAAI 2026 Oral

We introduce GSW, which equips LLMs with human-like episodic memory through structured semantic representations that track actors, roles, and states across space and time, outperforming standard RAG frameworks on episodic memory tasks.

We introduce DNARDE, a DNA language model trained with a contrastive objective for sequence alignment, pairing it with vector-store retrieval over nucleotide sequences. DNARDE outperforms prior transformer baselines on alignment and transfers across chromosomes and species.
