Semantic Memory Retrieval With Context Aware Recall

via “dual-memory-system-with-semantic-search”

End-to-end, code-first tutorials for building production-grade GenAI agents. From prototype to enterprise deployment.

Unique: Explicitly separates short-term (Redis) and long-term (vector DB) memory with configurable retrieval strategies, using RedisConfig and VectorStore abstractions — most frameworks conflate these into a single context window, losing the ability to scale memory independently

vs others: Outperforms naive RAG approaches (e.g., LangChain's memory classes) by decoupling recency from relevance; agents can access week-old memories if semantically similar while keeping recent context in fast Redis, reducing both latency and token waste

via “semantic-memory-retrieval-with-ranking”

Core memory palace engine for AgentRecall

Uses spatial memory palace structure to pre-filter candidates before ranking, reducing computation vs. flat vector search.

vs others: More sophisticated than simple vector similarity search because it weights recency and usage patterns, preventing old but semantically similar memories from drowning out recent relevant ones. Spatial pre-filtering reduces ranking computation vs. exhaustive similarity search.
