LLM Era Sees Rise of Retrieval Divergence Problem, Rank Fusion Key

The "Retrieval Divergence Problem" highlights a growing challenge in LLM-based systems where the information retrieved by a system diverges significantly from what the LLM actually needs. This issue is becoming more pronounced as LLMs become more sophisticated. The article argues that Rank Fusion, a technique that combines multiple ranking strategies, is crucial for mitigating this divergence and improving the overall performance of retrieval-augmented generation systems.
