Khái niệm cốt lõi
Large language models blur the lines between machine- and human-authored code, but DetectCodeGPT offers a novel method to detect machine-generated code by capturing distinct stylized patterns.
Tóm tắt
The article discusses the challenges posed by large language models in distinguishing between machine- and human-authored code. It introduces DetectCodeGPT, a method that strategically perturbs code with spaces and newlines to identify machine-generated code based on unique patterns. The study analyzes lexical diversity, conciseness, and naturalness in both types of code to highlight differences. Experimental results show DetectCodeGPT outperforms existing methods in detecting machine-generated code across various models and datasets.
