ZeroCoder: Can LLMs Improve Code Generation Without Ground-Truth Supervision?

Lishui Fan, Mouxiang Chen, Tingwei Zhu +4

Code generation is important in software engineering, and Reinforcement Learning with Verifiable Rewards (RLVR) is a powerful paradigm to improve it through execution-based feedbac…

ReCode: Reinforcing Code Generation with Reasoning-Process Rewards

Lishui Fan, Yu Zhang, Mouxiang Chen +1

In practice, rigorous reasoning is often a key driver of correct code, while Reinforcement Learning (RL) for code generation often neglects optimizing reasoning quality. Bringing p…

Balancing Latency and Accuracy of Code Completion via Local-Cloud Model Cascading

Hanzhen Lu, Lishui Fan, Jiachi Chen +3

Line-level code completion requires a critical balance between high accuracy and low latency. Existing methods suffer from a trade-off: large language models (LLMs) provide high-qu…

FGIT: Fault-Guided Fine-Tuning for Code Generation

Lishui Fan, Zhongxin Liu, Haoye Wang +3

Modern instruction-tuned large language models (LLMs) have made remarkable progress in code generation. However, these LLMs fine-tuned with standard supervised fine-tuning (SFT) so…

Parallel Scaling Law for Language Models

Mouxiang Chen, Binyuan Hui, Zeyu Cui +5

It is commonly believed that scaling language models should commit a significant space or time cost, by increasing the parameters (parameter scaling) or output tokens (inference-ti…

FlexFL: Flexible and Effective Fault Localization with Open-Source Large Language Models

Chuyang Xu, Zhongxin Liu, Xiaoxue Ren +3

Due to the impressive code comprehension ability of Large Language Models (LLMs), a few studies have proposed to leverage LLMs to locate bugs, i.e., LLM-based FL, and demonstrated…
