Xun Zheng



Welcome! I am a PhD student in the Machine Learning Department at the Carnegie Mellon University, advised by Eric Xing and Pradeep Ravikumar.

I am interested in all aspects of probabilistic models -- including inference, parameter learning, structure learning, and connections with neural networks.
