DQF (Dual-Index Query Framework) is a novel high-dimensional approximate nearest neighbor search framework that leverages a dual-layer index structure and dynamic search strategy based on a decision tree. It optimizes search efficiency by prioritizing high-frequency queries through a "hot index" and managing dynamic query distributions with an incremental update mechanism. This code forked off from code for NSSG algorithm.
