(My CV)

Bio: Wenlin Chen is now a fourth year Ph.D student in the Department of Computer Science and Engineering at Washington University in St. Louis. He works with Prof. Yixin Chen and Prof. Kilian Weinberger 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 2014, he was an intern in 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 in Microsoft Research Asia. Wenlin received the runner up for best student paper award in KDD14 and nomination for best paper award in ICDM13.

Software

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 a large-scale nonlinear classification method that supports for mix-type data and good interpretability.
