From the video description

This conceptual guide introduces three memory types useful for developing adaptive LLM agents. Understanding how to implement semantic, procedural, and episodic memory enables more precise control over agent knowledge, behavior, and learning capabilities. Semantic memory stores domain knowledge and contextual information, implemented either as searchable collections or compressed profiles. Collections enable vector search across unbounded datasets, while profiles optimize rapid context retrieval for user-facing applications.
