How Do LLMs Read Bug Reports? An Empirical Study of Attention in LLMs for Automated Program Repair
TL;DR
An empirical study reveals that Large Language Models (LLMs) for Automated Program Repair (APR) often misallocate attention in bug reports, leading to inconsistent repair outcomes. Successful repairs show diffused attention across various report sections, while failures focus too narrowly on metadata.
✦ Why It Matters
Focus on improving attention distribution in LLMs to enhance bug repair success rates.
Key Takeaways
- Analyze attention distribution in LLMs for better bug repair.
- Encourage broad attention across diagnostic components in models.
- Align model attention with developer insights for improved outcomes.
- Investigate attention misallocation as a factor in repair failures.
How It Works
The study employs empirical analysis of LLM attention patterns by examining bug reports, focusing on how attention is allocated across various sections. By comparing successful and unsuccessful repairs, the research identifies key components that LLMs should prioritize to enhance repair accuracy.
