Measuring AI Memory: Fusing BM25 with Graph Traversal
Updated: at 06:00 AMWhy pure graph traversal fails on long passages and pure vector search loses logical links, and how fusing SQLite FTS5 BM25 with graph BFS plus a dynamic token budget knapsack cutoff hit 92.3% recall in our offline setting.
Graph Traversal Without a Graph Database: BFS in Pure Python
Updated: at 07:00 AMWhy Neo4j is overkill for a personal AI agent's memory, and how to implement fast, multi-hop context retrieval using BFS in pure Python over SQLite.
Building a Deduplication Pipeline for Local Knowledge Graphs
Updated: at 06:00 AMWhy LLM extraction fails at knowledge graphs, and how a cascade of exact aliases, embeddings, and string fallback keeps local SQLite graphs clean.
Building a Local-First Memory Layer for AI Agents
Updated: at 08:00 AMA local-first memory layer for AI agents: SQLite WAL for durable triples plus an in-memory graph for retrieval. No server, no vector store, no graph database.
