I’m Wei Wen (温伟), a Ph.D. student in Duke University, supervised by Dr. Hai Helen Li and Dr. Yiran Chen. My research is Machine Learning and its applications in Computer Vision and Natural Language Processing. Recently, I focus on efficient deep learning on the edge, optimization algorithms for distributed machine learning, and learning algorithm understanding.
More specific, I proposed SmoothOut to escape sharp minima in deep neural networks to understand the generalization, TernGrad SGD to overcome the communication bottleneck in distributed machine learning, and regularization methods to learn structurally-sparse and lower-rank structures in deep neural networks for faster inference.
I had internship in Facebook Research, Microsoft Research Redmond & Asia and HP Labs, where I landed my research into industrial AI productions.
