Spectral Retrieval: Multi-Scale Sinc Convolution over Token Embeddings for Localized Retrieval in LLM Multi-Agent Systems
Researchers have introduced Spectral Retrieval, a novel method for enhancing information retrieval within Large Language Model (LLM) multi-agent systems. This technique employs multi-scale sinc convolution over token embeddings to interpolate between standard mean-pooling and per-token MaxSim retrieval. Spectral Retrieval significantly improves retrieval accuracy, particularly for localized relevance within documents, as demonstrated by its performance on synthetic and real-world benchmarks like LIMIT-small.
