Wenlin Chen's Homepage

[My C.V.]

Bio: Wenlin Chen is curently a research scientist at Facebook, working on machine learning. He obtained the PhD degree from Washington University in St. Louis. During the PhD study, he worked with Prof. Yixin Chen (Primary Advisor) and Prof. Kilian Weinberger (Now at Cornell) on machine learning and its applications. Before joining WashU, he got his bachelor degree in computer science from University of Science and Technology of China (USTC) in 2011. In 2015, he was an intern at Facebook AI Research (FAIR) doing research on deep learning with large output space with application on language modeling. In 2014, he was an intern at Google Research where he contributed to the development of a large-scale recommender system. From 2010 to 2011 when he was a senior undergrad, he also did some research on machine learning and Internet advertising at Microsoft Research Asia (MSRA). Wenlin received the runner up for best student paper award in KDD14 and nomination for best paper award in ICDM13.

MVC (Maximum Variance Correction)

Maximum Variance Correction finds large-scale feasible solutions to Maximum Variance Unfolding (MVU) by post-processing embeddings from any manifold learning algorithm. It increases the scale of MVU embeddings by several orders of magnitude and is naturally parallel.

FFD (Fast Flux Discriminant)

FFD is an interpretable machine learning method for large-scale nonlinear classification that supports mix-type data and feature sparsity.
