Logic Error Localization in Student Programming Assignments Using Pseudocode and Graph Neural Networks
Zhenyu Xu, Kun Zhang, Victor S. Sheng
Pseudocode is extensively used in introductory programming courses to instruct computer science students in algorithm design, utilizing natural language to define algorithmic behav…
LecPrompt: A Prompt-based Approach for Logical Error Correction with CodeBERT
Zhenyu Xu, Victor S. Sheng
Logical errors in programming don't raise compiler alerts, making them hard to detect. These silent errors can disrupt a program's function or cause run-time issues. Their correcti…
FreqMark: Frequency-Based Watermark for Sentence-Level Detection of LLM-Generated Text
Zhenyu Xu, Kun Zhang, Victor S. Sheng
The increasing use of Large Language Models (LLMs) for generating highly coherent and contextually relevant text introduces new risks, including misuse for unethical purposes such…
Signal Watermark on Large Language Models
Zhenyu Xu, Victor S. Sheng
As Large Language Models (LLMs) become increasingly sophisticated, they raise significant security concerns, including the creation of fake news and academic misuse. Most detectors…
Multi-Task Program Error Repair and Explanatory Diagnosis
Zhenyu Xu, Victor S. Sheng
Program errors can occur in any type of programming, and can manifest in a variety of ways, such as unexpected output, crashes, or performance issues. And program error diagnosis c…
