Reasoning Through Execution: Unifying Process and Outcome Rewards for Code Generation

ICML 2025poster

Large Language Models excel at code generation yet struggle with complex programming tasks that demand sophisticated reasoning. To bridge this gap, traditional process supervision relies on learned reward models requiring costly training data and suffering from reward misalignment, while outcome su…

FreeEval: A Modular Framework for Trustworthy and Efficient Evaluation of Large Language Models

EMNLP 2024system demonstrations

The rapid growth of evaluation methodologies and datasets for large language models (LLMs) has created a pressing need for their unified integration. Meanwhile, concerns about data contamination and bias compromise the trustworthiness of evaluation findings, while the efficiency of evaluation proces…

PandaLM: An Automatic Evaluation Benchmark for LLM Instruction Tuning Optimization

ICLR 2024poster

Instruction tuning large language models (LLMs) remains a challenging task, owing to the complexity of hyperparameter selection and the difficulty involved in evaluating the tuned models. To determine the optimal hyperparameters, an automatic, robust, and reliable evaluation benchmark is essential.…

RAGLAB: A Modular and Research-Oriented Unified Framework for Retrieval-Augmented Generation

EMNLP 2024system demonstrations

Large Language Models (LLMs) demonstrate human-level capabilities in dialogue, reasoning, and knowledge retention. However, even the most advanced LLMs face challenges such as hallucinations and real-time updating of their knowledge. Current research addresses this bottleneck by equipping LLMs with…
