About Me

I am conducting my doctoral research with the Statistics and Machine Learning Laboratory at Graduate School of Informatics, Kyoto University, supervised by Prof. Junya Honda.
My current research interests are mainly in learning theory and online optimization.
I received my Master’s Degree in Computer Technology, at School of Computer Science and Technology, Harbin Institute of Technology (Shenzhen), supervised by Prof. Qing Liao.
I received my Bachelor’s Degree in Computer Science and Technology, at School of Computer Science, SWPU in 2022.

Research Area

Algorithm Intern (2024.04-2024.07), Tencent, PCG Department, QQ short video recommendation. I’m mainly responsible for the multi-objective fusion (MTF) of precision ranking scores based on implicit Q-learning (IQL) reinforcement learning algorithm.

FedCom: A new method of multi-task clustered federated learning. In this method, we perform dynamic partition of clusters based on community detection, which can alleviate the negative impact caused by the early-stage partition errors.
FedAO: A toolbox for federated learning, aiming to provide implementations of FedAvg, FedProx, Ditto, etc. in multiple versions, such as Pytorch/Tensorflow, single-machine/distributed, synchronized/asynchronous and so on.
Numerical Analysis: A project for the implementation of the algorithm in the numerical analysis (by Timothy Sauer) using Python+Numpy+Pytorch.
