Xi-Zhu Wu (X.-Z. Wu) PhD Candidate LAMDA Group Department of Computer Science National Key Laboratory for Novel Software Technology Nanjing University email: wuxz # lamda.nju.edu.cn (gmail account "wuxz.gm")

Currently I am a final year PhD student of Department of Computer Science and Technology in Nanjing University and a member of LAMDA Group (LAMDA Publications), led by Professor Zhi-Hua Zhou.

I defended my PhD dissertation at 2020-08-24. I will work as a data scientist at Optiver Shanghai, which is a proprietary trading firm and market maker.

Research Interest

I am interested in machine learning. Currently I am focusing on the subfields:

• Model Reuse : Towards helping target task by reusing source models without source data. It is a topic in learnware.
• Multi-Label Learning : Learning from objects with multiple labels.

Besides, I have a good sense of measuring learning models.
