Beyond Token Length: Step Pruner for Efficient and Accurate Reasoning in Large Language Models

Canhui Wu, Qiong Cao, Chang Li +5

Large Reasoning Models (LRMs) demonstrate strong performance on complex tasks but often suffer from excessive verbosity, known as "overthinking." Existing solutions via reinforceme…

Efficient Reasoning via Thought-Training and Thought-Free Inference

Canhui Wu, Qiong Cao, Chao Xue +2

Recent advances in large language models (LLMs) have leveraged explicit Chain-of-Thought (CoT) prompting to improve reasoning accuracy. However, most existing methods primarily foc…

ChartMaster: Advancing Chart-to-Code Generation with Real-World Charts and Chart Similarity Reinforcement Learning

Wentao Tan, Qiong Cao, Chao Xue +3

The chart-to-code generation task requires MLLMs to convert chart images into executable code. This task faces two main challenges: limited data diversity and the difficulty of mai…

From Answers to Rationales: Self-Aligning Multimodal Reasoning with Answer-Oriented Chain-of-Thought

Wentao Tan, Qiong Cao, Yibing Zhan +2

Achieving human-like reasoning capabilities in Multimodal Large Language Models (MLLMs) has long been a goal. Current methods primarily focus on synthesizing positive rationales, t…

Learning Temporal Abstractions via Variational Homomorphisms in Option-Induced Abstract MDPs

Chang Li, Yaren Zhang, Haoran Lv +3

Large Language Models (LLMs) have shown remarkable reasoning ability through explicit Chain-of-Thought (CoT) prompting, but generating these step-by-step textual explanations is co…

Beyond Human Data: Aligning Multimodal Large Language Models by Iterative Self-Evolution

Wentao Tan, Qiong Cao, Yibing Zhan +2

Human preference alignment can greatly enhance Multimodal Large Language Models (MLLMs), but collecting high-quality preference data is costly. A promising solution is the self-evo…
