Four agent memory types: sensory, working, episodic, semantic
Agent Memory — From Context Window to Vector Store
Introduction
Cognitive scientists identified four memory types in humans; AI agent researchers mapped them to concrete architecture components. Sensory memory is raw input data for a fraction of a second; working memory is the active "workbench" (context window); episodic memory is autobiographical past events; semantic memory is general domain knowledge. This lesson shows how each type is realised in agent systems.
