I’m Wei Wen (温伟), a Ph.D. student in Duke University, supervised by Dr. Hai Li and Dr. Yiran Chen. My current research focuses on scalable and efficient machine learning for cloud-edge AI systems. I’m interested in Machine Learning in general.
Recently, I worked on scalable distributed deep learning and model compression & acceleration. More specific, I proposed TernGrad SGD to overcome the communication bottleneck in distributed deep learning, and worked on optimization methods to learn structurally-sparse and lower-rank deep neural networks for faster inference.
I had internship in Microsoft Research at Redmond, and HP Labs at Palo Alto.
