Bridging Restoration and Diagnosis: A Comprehensive Benchmark for Retinal Fundus Enhancement

Xuanzhao Dong, Wenhui Zhu, Xiwen Chen +8

Over the past decade, generative models have demonstrated success in enhancing fundus images. However, the evaluation of these models remains a challenge. A benchmark for fundus im…

OTPrune: Distribution-Aligned Visual Token Pruning via Optimal Transport

Xiwen Chen, Wenhui Zhu, Gen Li +9

Multi-modal large language models (MLLMs) achieve strong visual-language reasoning but suffer from high inference cost due to redundant visual tokens. Recent work explores visual t…

Distilling the Essence: Efficient Reasoning Distillation via Sequence Truncation

Wei-Rui Chen, Vignesh Kothapalli, Ata Fatahibaarzi +5

Distilling the capabilities from a large reasoning model (LRM) to a smaller student model often involves training on substantial amounts of reasoning data. However, knowledge disti…

VAOT: Vessel-Aware Optimal Transport for Retinal Fundus Enhancement

Xuanzhao Dong, Wenhui Zhu, Yujian Xiong +8

Color fundus photography (CFP) is central to diagnosing and monitoring retinal disease, yet its acquisition variability (e.g., illumination changes) often degrades image quality, w…

Planner-R1: Reward Shaping Enables Efficient Agentic RL with Smaller LLMs

Siyu Zhu, Yanbin Jiang, Hejian Sang +6

We investigated Agentic RL with large language models on the \textsc{TravelPlanner} benchmark. Our approach, \textsc{Planner-R1}, achieved a \textbf{56.9\%} final-pass rate with on…

Reasoning Models Can be Accurately Pruned Via Chain-of-Thought Reconstruction

Ryan Lucas, Kayhan Behdin, Zhipeng Wang +3

Reasoning language models such as DeepSeek-R1 produce long chain-of-thought traces during inference time which make them costly to deploy at scale. We show that using compression t…

EVTP-IVS: Effective Visual Token Pruning For Unifying Instruction Visual Segmentation In Multi-Modal Large Language Models

Wenhui Zhu, Xiwen Chen, Zhipeng Wang +5

Instructed Visual Segmentation (IVS) tasks require segmenting objects in images or videos based on natural language instructions. While recent multimodal large language models (MLL…

LLaDA-MedV: Exploring Large Language Diffusion Models for Biomedical Image Understanding

Xuanzhao Dong, Wenhui Zhu, Xiwen Chen +5

Autoregressive models (ARMs) have long dominated the landscape of biomedical vision-language models (VLMs). Recently, masked diffusion models such as LLaDA have emerged as promisin…
