INSIDE LINKEDIN'S COGNITIVE MEMORY AGENT FOR AGENTIC PERSONALIZATION (32 MINUTE PODCAST)

Summary from the TLDR Data newsletter

LinkedIn built a cognitive memory agent that personalizes its hiring assistant using four layers: conversational, episodic, semantic, and procedural memory. It replaced GraphRAG with a hierarchical tree that supports cheaper incremental updates, while dedicated ingestion, consolidation, and retrieval services keep preferences fresh, traceable, access-controlled, and available within tight latency limits.
