Lin Xiaoqiang

PhD student, National University of Singapore

I am a third-year PhD student from National University of Singapore, advised by Assoc. Prof. Bryan Low and Prof. See-Kiong Ng. Before that, I was a full time machine learning engineer at Ant Group. I received my Bachelor's degree from the Fudan University, where I worked with Assoc. Prof. Zhongyu Wei.


[5 Oct 2023] Our instruction optimization paper (INSTINCT) is avaliable on arxiv now.

[10 Aug 2023] I receive Research Achievement Award from NUS School of Computing.

[8 Aug 2023] Our paper "Federated Zeroth-Order Optimization using Trajectory-Informed Surrogate Gradients" is avaliable on arxiv now.

[24 Apr 2023] Our paper "Fair yet Asymptotically Equal Collaborative Learning" is accepted by ICML 2023.

Research Interest

I am broadly interested in research on the Collaborative Machine Learning, Data Valuation, Zeroth-Order Optimization. I used to work on Natrual Language Processing and Social Computing.
