Chun-Nam Yu


Chun-Nam Yu joined Bell Labs as a Member of Technical Staff in 2012. He received his BA degree in Mathematics and Computer Science from Oxford University in 2004, and PhD degree in Computer Science in 2010 from Cornell University, under the supervision of Thorsten Joachims. He was a postdoctoral fellow at the Alberta Innovates Centre of Machine Learning (AICML) at the University of Alberta from 2010 to 2012, working with Russ Greiner on biomedical machine learning problems. His research interests include structured output prediction, support vector machines, kernel methods, and on the large-scale training of these models. At Bell Labs he studied time series modeling problems arising from network traffic and smart grid data, and also the online optimization of network diagnostic processes.
