REVERSIBLE INC

Hello, this is Weixin Bu (Also, Bryson), an ordinary but curious person.

I work at REVERSIBLE INC as a [Search and Recommendation Engineer]. I am now working on the pipeline construction, performance optimization and multimodal implementation of the search and recommendation systems. Additionally, I am exploring innovative applications of LLMs for automated code bug fix, while also working on advanced image generation technologies.

I graduated from School of Computer and Software, Nanjing University of Information Science and Technology (南京信息工程大学计算机与软件学院) with a bachelor’s degree; and from School of Artificial Intelligence, Jilin University (吉林大学人工智能学院) with a master’s degree.

I am passionate about researching on Artificial Intelligence and Software Development. My research interests include Graph Neural Networks (GNNs), Self/Semi-supervised Learning, Multimodal Learning, and Large Foundation Models, etc.

Nonparametric Teaching for Graph Property Learners
Chen Zhang*, Weixin Bu*, Zeyi Ren, Zhengwu Liu, Yik-Chung Wu, Ngai Wong
[Project] | [Code]

  • A novel paradigm that interprets graph property learning within the theoretical context of nonparametric teaching (NT)
  • Reveal the consistency between the evolution of GCN driven by parameter updates and that under functional gradient descent in NT
  • Demonstrate the effectiveness of GraNT through extensive experiments (graph/node-level regression / classification) in graph property learning
