Lin Chen (陈林)

Greetings! I'm currently a PhD student in School of Automation, University of Science and Technology of China, advised by Prof. Feng Zhao. I got a B.E. degree at Anhui University in 2020 and join the USTC-BIVLab. And I serve as an research intern in Shanghai AI Laboratory now, supervised by Dr. Jiaqi Wang and Dr. Pan Zhang.

My research interest includes:

• image semantic segmentation
• transfer learning and parameter-efficient fine-tuning
• vision-language models

* indicates the equal contribution.

A versatile large-vision language model that supports long-contextual input and output. IXC-2.5 excels in various text-image comprehension and composition applications, achieving GPT-4V level capabilities with merely 7B LLM backend.

We propose the ShareGPT4V project, comprising 100K GPT4-Vision-generated captions, 1.2M high-quality captions, a general image captioner, and a superior large multi-modal model, ShareGPT4V-7B

We present Prism, an innovative framework designed to disentangle the perception and reasoning processes involved in visual question solving.

A large-scale highly descriptive video-text dataset, with 40K captions annotated by GPT4V and 4.8M captions annotated by our ShareCaptioner-Video. The total videos last with 300 hours and 3000 hours separately!

We identify two primary issues in existing evaluation studies for large vision-language models. We further develop an elite vision-indispensable multi-modal benchmark and two novel metrics to measure data leakage and actual performance gain in multi-modal training.

We propose the Rein framework, which efficiently fine-tunes vision foundation models for the domain generalized semantic segmentation (DGSS) task with just 1% trainable parameters, surprisingly surpassing full parameter fine-tuning. And Reins builds a new SOTA in various DGSS benchmarks.

We propose a novel "drag" editing framework called FreeDrag free of the burden of erroneous point tracking and enables achieving stable point-based editing in challenging scenarios with similar structures, fine details, or under multi-point targets.

We propose a novel nigh-time semantic segmentation paradigm, i.e., disentangle then parse (DTP), which explicitly disentangles night-time images into light-invariant reflectance and light-specific illumination components and then recognizes semantics based on their adaptive fusion.

We leverage the complementary characteristics of the coarse-wise and fine-wise data mixing techniques to progressively transfer the knowledge from the source to the target domain.

We reuse the category classifier as a discriminator to form a discriminator-free adversarial learning framework.
