Researchers have developed DRAG, a novel framework designed to dynamically adapt retriever and generator configurations in Retrieval-Augmented Generation (RAG) systems. Unlike traditional RAG systems that use fixed settings, DRAG analyzes query complexity to optimize resource allocation. The framework includes a training-free approach, DRAG$_ ext{QPP}$, which uses Query Performance Prediction and perplexity measures, and a supervised approach, DRAG$_ ext{SFT}$, which fine-tunes an LLM for configuration prediction. Experiments across multiple LLM families and benchmarks show that DRAG can achieve comparable or improved effectiveness while significantly reducing inference latency compared to static RAG pipelines.
