Abstract
The content delves into the evaluation of non-functional properties in Large Language Models for Code (LLM4Code), focusing on robustness, security, privacy, explainability, efficiency, and usability. It discusses the impact of these properties on software engineering tasks and presents methods to enhance them. The study emphasizes the importance of considering these aspects beyond accuracy when developing and evaluating language models for code.
Key points include:
LLM4Code's transformational impact on software engineering.
Evaluation of seven important properties beyond accuracy.
Methods to evaluate and enhance robustness, security, privacy, explainability, efficiency, and usability.
Challenges and future research opportunities in studying non-functional properties.
The study also highlights the need for scalable methods to protect large models with billions of parameters against threats like data poisoning attacks. Additionally, it emphasizes the significance of human review alongside automated detection methods to mitigate security risks posed by malicious attacks on LLM4Code.
Stats
LLM4Code suffer from low robustness issue.
LLM4Code is at risk due to security threats like data poisoning; The ease of access and possibility of alteration of training data by attackers increase this vulnerability.
LLM4Code can leak sensitive information like personal privacy (e.g., emails, passwords, IP addresses) and effectiveness of existing mitigation strategies is unclear.
There exists noted inconsistency among explanations provided by different techniques, highlighting the need for more reliable methods.
Parameter-Efficient Fine-tuning is gaining popularity for enhancing the training efficiency of LLM4Code.
The impact of LLM4Code on productivity is mixed.
