Model Calibration Measurement Across Confidence Metrics

via “similarity score normalization and calibration”

Self-learning vector database for Node.js — hybrid search, Graph RAG, FlashAttention-3, HNSW, 50+ attention mechanisms

Unique: Implements statistical calibration of similarity scores based on query patterns, whereas most vector DBs return raw distances without normalization or confidence interpretation

vs others: More principled than manual threshold tuning; simpler than building separate ranking models because calibration is automatic
