I’m Wei Wen (温伟), a Research Scientist at Meta AI. Our team applies AI to both research problems in academia and to real-world problems at Facebook scale. I obtained my Ph.D. degree from Duke University in 2019. My research is Deep Learning with its applications to computer vision, recommender systems, natural language processing, and others. More specific, I work on Automated Machine Learning (AutoML), efficient deep neural networks, and distributed deep learning. I spent some time at Google Brain, Facebook AI, Microsoft Research and HP Labs.
