An Information Bottleneck Perspective for Effective Noise Filtering on Retrieval-Augmented Generation

ACL 2024long

Retrieval-augmented generation integrates the capabilities of large language models with relevant information retrieved from an extensive corpus, yet encounters challenges when confronted with real-world noisy data. One recent solution is to train a filter module to find relevant content but only ac…
