Fixing the Broken Compass: Diagnosing and Improving Inference-Time Reward Modeling

ICLR 2026poster

Inference-time scaling techniques have shown promise in enhancing the reasoning capabilities of large language models (LLMs). While recent research has primarily focused on training-time optimization, our work highlights inference-time reward model (RM)-based reasoning as a critical yet overlooked a…

MMR-Life: Piecing Together Real-life Scenes for Multimodal Multi-image Reasoning

ICLR 2026poster

Recent progress in the reasoning capabilities of multimodal large language models (MLLMs) has empowered them to address more complex tasks such as scientific analysis and mathematical reasoning. Despite their promise, MLLMs’ reasoning abilities across different scenarios in real life remain largely…

MMR-V: What's Left Unsaid? A Benchmark for Multimodal Deep Reasoning in Videos

ICLR 2026poster

The sequential structure of videos poses a challenge to the ability of multimodal large language models (MLLMs) to locate multi-frame evidence and conduct multimodal reasoning. However, existing video benchmarks mainly focus on understanding tasks, which only require models to match frames mentioned…

Omni-Reward: Towards Generalist Omni-Modal Reward Modeling with Free-Form Preferences

ICLR 2026oral

Reward models (RMs) play a critical role in aligning AI behaviors with human preferences, yet they face two fundamental challenges: (1) Modality Imbalance, where most RMs are mainly focused on text and image modalities, offering limited support for video, audio, and other modalities; and (2) Prefere…

MIRAGE: Evaluating and Explaining Inductive Reasoning Process in Language Models

ICLR 2025poster

Inductive reasoning is an essential capability for large language models (LLMs) to achieve higher intelligence, which requires the model to generalize rules from observed facts and then apply them to unseen examples. We present {\scshape Mirage}, a synthetic dataset that addresses the limitations of…

Towards Better Chain-of-Thought: A Reflection on Effectiveness and Faithfulness

ACL 2025finding

Chain-of-thought (CoT) prompting demonstrates varying performance under different reasoning tasks.Previous work attempts to evaluate it but falls short in providing an in-depth analysis of patterns that influence the CoT. In this paper, we study the CoT performance from the perspective of effectiven…

Focus on Your Question! Interpreting and Mitigating Toxic CoT Problems in Commonsense Reasoning

ACL 2024long

Large language models exhibit high-level commonsense reasoning abilities, especially with enhancement methods like Chain-of-Thought (CoT). However, we find these CoT-like methods lead to a considerable number of originally correct answers turning wrong, which we define as the Toxic CoT problem. To i…

LINKED: Eliciting, Filtering and Integrating Knowledge in Large Language Model for Commonsense Reasoning

EMNLP 2024finding

Large language models (LLMs) sometimes demonstrate poor performance on knowledge-intensive tasks, commonsense reasoning is one of them. Researchers typically address these issues by retrieving related knowledge from knowledge graphs or employing self-enhancement methods to elicit knowledge in LLMs.…

Leros: Learning Explicit Reasoning on Synthesized Data for Commonsense Question Answering

COLING 2024main

Recent work shows large language models can be prompted to generate useful rationales for commonsense question answering (CQA), which can improve the performance of both themselves and other models. However, the cost of deployment and further tuning is relatively expensive for the large models. Some…

RWKU: Benchmarking Real-World Knowledge Unlearning for Large Language Models

NeurIPS 2024poster

Large language models (LLMs) inevitably memorize sensitive, copyrighted, and harmful knowledge from the training corpus; therefore, it is crucial to erase this knowledge from the models. Machine unlearning is a promising solution for efficiently removing specific knowledge by post hoc modifying mode…

CN-AutoMIC: Distilling Chinese Commonsense Knowledge from Pretrained Language Models

EMNLP 2022main

Commonsense knowledge graphs (CKGs) are increasingly applied in various natural language processing tasks. However, most existing CKGs are limited to English, which hinders related research in non-English languages. Meanwhile, directly generating commonsense knowledge from pretrained language models…
