I’m Wei Wen (温伟), a Ph.D. candidate 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 understanding learning algorithms, structural learning for accurate and efficient deep neural networks, and optimization algorithms for distributed deep learning.
More specific, I study learning algorithms to escape sharp minima in deep neural networks to understand the generalization, TernGrad SGD to overcome the communication bottleneck in distributed machine learning, and structural leaning algorithms to learn sparse and low-rank structures in deep neural networks for faster inference.
My Ph.D. thesis is “Efficient and Scalable Deep Learning“. Dissertation committee: Hai Helen Li, Yiran Chen, Robert Calderbank, Yangqing Jia and Guillermo Sapiro.
I will intern at Google Brain in this summer. I enjoyed research internships in Facebook Research, Microsoft Research Redmond & Asia, and HP Labs, where I incorporated my research into industrial AI productions.
