Verifier-Induced Support Reshaping in On-Policy Optimization

Shaohang Wei, Zikun Su, Feifan Song +4

We show that on-policy reinforcement learning with verifiable rewards (RLVR) can improve the current objective while making successful behaviors for later objectives too rare to sa…

Encode Errors: Representational Retrieval of In-Context Demonstrations for Multilingual Grammatical Error Correction

Guangyue Peng, Wei Li, Wen Luo +1

Grammatical Error Correction (GEC) involves detecting and correcting the wrong usage of grammar. While large language models (LLMs) with in-context learning (ICL) capabilities have…

Only Say What You Know: Calibration-Aware Generation for Long-Form Factuality

Wen Luo, Guangyue Peng, Liang Wang +7

Large Reasoning Models achieve strong performance on complex tasks but remain prone to hallucinations, particularly in long-form generation where errors compound across reasoning s…

Measuring and Mitigating Post-hoc Rationalization in Reverse Chain-of-Thought Generation

Guangyue Peng, Zongchao Chen, Wen Luo +9

Reverse Chain-of-Thought Generation (RCG) synthesizes reasoning traces from query-answer pairs, but answer-visible generation can justify a pre-committed answer rather than derive…

Two Pathways to Truthfulness: On the Intrinsic Encoding of LLM Hallucinations

Wen Luo, Guangyue Peng, Wei Li +8

Despite their impressive capabilities, large language models (LLMs) frequently generate hallucinations. Previous work shows that their internal states encode rich signals of truthf…

Mitigating Overthinking through Reasoning Shaping

Feifan Song, Shaohang Wei, Bofei Gao +8

Large reasoning models (LRMs) boosted by Reinforcement Learning from Verifier Reward (RLVR) have shown great power in problem solving, yet they often cause overthinking: excessive,…

TIME: A Multi-level Benchmark for Temporal Reasoning of LLMs in Real-World Scenarios

Shaohang Wei, Wei Li, Feifan Song +5

Temporal reasoning is pivotal for Large Language Models (LLMs) to comprehend the real world. However, existing works neglect the real-world challenges for temporal reasoning: (1) i…

FEA-Bench: A Benchmark for Evaluating Repository-Level Code Generation for Feature Implementation

Wei Li, Xin Zhang, Zhongxin Guo +6

Implementing new features in repository-level codebases is a crucial application of code generation models. However, current benchmarks lack a dedicated evaluation framework for th…

Explanation based In-Context Demonstrations Retrieval for Multilingual Grammatical Error Correction

Wei Li, Wen Luo, Guangyue Peng +1

Grammatical error correction (GEC) aims to correct grammatical, spelling, and semantic errors in natural language text. With the growing of large language models (LLMs), direct tex…

Detection-Correction Structure via General Language Model for Grammatical Error Correction

Wei Li, Houfeng Wang

Grammatical error correction (GEC) is a task dedicated to rectifying texts with minimal edits, which can be decoupled into two components: detection and correction. However, previo…
