Deep learning models struggle with large-scale code retrieval, new paper finds

A new research paper titled "Recall Before Rerank" evaluates the performance of deep learning models for large-scale code-to-code retrieval. The study highlights limitations in the precision and scalability of current models when dealing with terabyte-scale source code collections across various programming languages. Researchers propose LLM-based techniques for code normalization and query rewriting to improve the performance of less effective models, questioning the viability of resource-constrained deployments for specialized code LLMs. AI

IMPACT Highlights limitations in current LLMs for code retrieval, suggesting areas for improvement in scalability and precision for developers.
