R-Zero: Self-Evolving Reasoning LLM from Zero Data

ICLR 2026poster

Self-evolving Large Language Models (LLMs) offer a scalable path toward super-intelligence by autonomously generating, refining, and learning from their own experiences. However, existing methods for training such models still rely heavily on vast human-curated tasks and labels, typically via fine-t…

FG-PRM: Fine-grained Hallucination Detection and Mitigation in Language Model Mathematical Reasoning

EMNLP 2025

Hallucinations in large language models (LLMs) pose significant challenges in tasks requiring complex multi-step reasoning, such as mathematical problem-solving. Existing approaches primarily detect the presence of hallucinations but lack a nuanced understanding of their types and manifestations. In

FaithScore: Fine-grained Evaluations of Hallucinations in Large Vision-Language Models

EMNLP 2024finding

We introduce FaithScore (Faithfulness to Atomic Image Facts Score), a reference-free and fine-grained evaluation metric that measures the faithfulness of the generated free-form answers from large vision-language models (LVLMs). The FaithScore evaluation first identifies sub-sentences containing des…

IQA-EVAL: Automatic Evaluation of Human-Model Interactive Question Answering

NeurIPS 2024poster

To evaluate Large Language Models (LLMs) for question answering (QA), traditional methods typically focus on directly assessing the immediate responses generated by the models based on the given question and context. In the common use case of humans seeking AI assistant’s help in finding information…

MEQA: A Benchmark for Multi-hop Event-centric Question Answering with Explanations

NeurIPS 2024poster

Existing benchmarks for multi-hop question answering (QA) primarily evaluate models based on their ability to reason about entities and the relationships between them. However, there's a lack of insight into how these models perform in terms of both events and entities. In this paper, we introduce a…

Leveraging Structured Information for Explainable Multi-hop Question Answering and Reasoning

EMNLP 2023long findings

Neural models, including large language models (LLMs), achieve superior performance on multi-hop question-answering. To elicit reasoning capabilities from LLMs, recent works propose using the chain-of-thought (CoT) mechanism to generate both the reasoning chain and the answer, which enhances the mod…
