Memory Retrieval in AI Agents

Memory retrieval is how agents access relevant past information to inform current decisions. Instead of processing all past data (slow), agents search for relevant items. Vector similarity search is common: encode current context and past events as vectors, find closest matches.

A tutoring agent retrieving memory: "Student struggled with quadratic equations before. How did we solve it?" Agent searches: past interactions with "quadratic equations" → finds previous explanation → adapts and reuses successful strategy.

RAG (Retrieval-Augmented Generation) combines retrieval with generation: fetch relevant documents, use them to inform LLM responses. A code-helping agent might: "Student needs help with loops" → retrieve relevant Python tutorial snippets → generate customized explanation using those snippets.
