Sicong Liu刘思聪

I'm currently an associate professor in the School of Computer Science at Northwestern Polytechnical University (NPU). Before joining NPU, I received my Ph.D. degree from Xidian University, China, in 2020. And I had an experience as a joint PhD student at Rice University.


I care about the knowledge discoveries towards building ubiquitous deep learning system for benefiting common users and reducing the workload of developers.
