CoHyDE: Iterative Co-Training of LLM Rewriter & Dense Encoder for Tool Retrieval
Researchers introduce CoHyDE, an iterative co-training method that jointly optimizes a dense encoder and LLM rewriter to improve tool retrieval for AI agents. The approach outperforms single-component baselines by 2.5-8 percentage points on standard and vague queries, addressing the fundamental challenge of bridging colloquial user language with technical API vocabularies.
