About Me

Currently I am a first-year Ph.D. student of Department of Computer Science and Technology and a member of LAMDA Group, led by professor Zhi-Hua Zhou . Before my Ph.D. career, I was an undergraduate student of Kuang Yaming Honors School, Nanjing University and received my B.Sc. degree in Computer Science and Technology in June 2018. In the same year, I was admitted to study for a Ph.D. degree in Nanjing University without entrance examination.

Works


chuangxin 
  • I've joined Sinovation AI Institute as a quantitative research intern. My work focuses on building a simulated A-share market using Reinforcement Learning related techniques.

Julia 
  • Julia language is a rapidly developing programming language featured as efficient numerical computing and multiple dispatch. I am an active developer of Julia community. Now I’m building a mirror website hosted on the Chinese educational network for accelerating visiting speed of Julia websites and download speed of Julia packages.

meridian 
  • In the course of cooperative research with Meridian Global Inc - YRTech , 2018, I built a distributed optimization system for finding effective factors at Chinese A-share Market. Now I’m still working with a group on this project. Satisfactory results appeared when doing back test and the system will be used at the real A-share market soon.
ZOOpt 
  • I am the core developer of the open source python package ZOOpt, which provides efficient derivative-free solvers and is designed easy to use . ZOOpt toolbox particularly focuses on optimization problems in machine learning, addressing high-dimensional, noisy, and large-scale problems.
