Welcome! My name is Wenjie Hu and I am a master of Computer Science and Technology at Zhejiang University. My research interests lie in mining deep knowledge from large-scale data, which focus on Time Series Modeling and Graph Embedding. I obtained my bachelor degree from Harbin Institute of Technology in 2017, and master degree from Zhejiang University in 2020, advised by Yang Yang. During my master career, I have published one paper and conducted an internship in State Grid of China. For more detailed personal information, please refer to my resume.

Graph embedding, also known as network representation learning, aims to learn the low-dimensional representations of vertexes in a network, while structure and inherent properties of the graph is preserved.
Our research mainly focuses on learning representations for social networks. Social networks are scale-free: vertex degrees of a social network follow a heavy-tailed distribution. Is it possible to reconstruct a scale-free network according to the learned vertex embedding? We first theoretically analyze the difficulty of embedding and reconstructing a scale-free network in the Euclidean space, by converting our problem to the sphere packing problem. Then, we propose the "degree penalty" principle for designing scale-free property preserving network embedding algorithm: punishing the proximity between high-degree vertexes. We introduce two implementations of our principle by utilizing the spectral techniques and a skip-gram model respectively (Feng et al., AAAI'18).
