Dr. Chen XU is dedicated to applying mathematical statistics, signal processing (including Fourier transform, and wavelet analysis), machine learning, as well as their applications in other fields. His past research topics include stochastic discount factor models, time series analysis, fund research, etc. Now he mainly works on supervised learning algorithms in applied mathematics and analyzing the convergence of reinforcement learning algorithms using probability theory, time series, and topology. He has published several papers as the first or corresponding author in top-tier journals and international conferences.

徐晨博士致力于应用数理统计、信号处理（傅里叶变换、小波分析）、机器学习等方法以及它们在其他领域中的应用。以往研究课题包括随机贴现因子模型、时间序列分析、基金研究等。当前工作主要包括使用概率论、时间序列、拓扑等工具对强化学习算法收敛性进行分析，以及监督学习算法在应用数学等领域的应用研究。他以第一或通讯作者在中国数学会推荐的T1类期刊或中国计算机学会推荐的A类会议(CVPR)上发表论文。
