Retrieval-Enhanced Transformers (RETRO): A Semi-Parametric

Retrieval-Enhanced Transformers (RETRO): A Semi-Parametric Approach to Enhance Performance of Large Language Models

Listen now

Description

The paper introduces the RETRO model, which leverages retrieval from a massive text database to enhance large language model performance without increasing model size. Key takeaways include the benefits of linear time complexity for retrieval, the use of frozen BERT for efficient retrieval, and the importance of addressing test set leakage in evaluation.
