CoVStream: Edge-Cloud Collaboration for Understanding of Long Video Streams
Xu Liu, Guikun Chen, Zihao Yan +2
The paper introduces CoVStream, an edge‑cloud system that compresses raw video into compact visual features and captions on the device, sends them to the cloud for graph‑based reas…
Tractogram foundation model
Guikun Chen, Yuqian Chen, Yijie Li +5
Diffusion MRI (dMRI) tractography is the only noninvasive approach for mapping white-matter pathways in the living human brain. It represents each brain as a tractogram: a large, u…
SinkTrack: Attention Sink based Context Anchoring for Large Language Models
Xu Liu, Guikun Chen, Wenguan Wang
Large language models (LLMs) suffer from hallucination and context forgetting. Prior studies suggest that attention drift is a primary cause of these problems, where LLMs' focus sh…
A Survey on 3D Gaussian Splatting
Guikun Chen, Wenguan Wang
3D Gaussian splatting (GS) has emerged as a transformative technique in radiance fields. Unlike mainstream implicit neural models, 3D GS uses millions of learnable 3D Gaussians for…
Chemical knowledge-informed framework for privacy-aware retrosynthesis learning
Guikun Chen, Xu Zhang, Xiaolin Hu +3
Chemical reaction data is a pivotal asset, driving advances in competitive fields such as pharmaceuticals, materials science, and industrial chemistry. Its proprietary nature rende…
SEED-GRPO: Semantic Entropy Enhanced GRPO for Uncertainty-Aware Policy Optimization
Minghan Chen, Guikun Chen, Wenguan Wang +1
Large language models (LLMs) exhibit varying levels of confidence across input prompts (questions): some lead to consistent, semantically similar answers, while others yield divers…
