Long Shi
I am an assistant professor at the School of Computing and Artificial Intelligence at Southwestern University of Finance and Economics. My research interests lie at the intersection of signal processing and machine learning.
I received my Doctoral degree from the School of Electricity Engineering at Southwest Jiaotong University. From 2018 to 2019, I was a visiting student at the University of York under the supervision of Prof. Yuriy Zakharov. I have published several high-quality papers in IEEE TSP, IEEE SPL, IEEE TCSII, SP, DSP, etc. My homepage on Southwestern University of Finance and Economics can be found in myswufe.

Research
My research focuses on the intersection of signal processing and machine learning. Specifically, I am interested in adaptive signal processing, including algorithm optimization and applications. Additionally, I am interested in machine learning techniques such as subspace clustering, multi-view learning, multimodal learning, and reinforcement learning. Currently, I am also focusing on LLM.
