Chih-Jen Lin () is a Taiwanese computer scientist who is a distinguished professor of computer science at National Taiwan University, and a leading researcher in machine learning, optimization, and data mining. He is best known for the open-source library LIBSVM, an implementation of support vector machines. With his students he also developed LIBLINEAR, a widely used library for large-scale linear classification.
Biography Chih-Jen Lin earned a B.S. (1993) in mathematics at National Taiwan University, and an M.S.E. (1996) and a Ph.D. (1998) in Industrial and Operations Engineering at the University of Michigan.
Lin's machine-learning software has been adopted by industry, with his libraries used by Yahoo, Google, eBay, and Microsoft. He has held visiting research positions, as a visiting scientist at Yahoo! Research (2006–2007) and visiting professor at Google Research (2008), and as a visiting scholar at Alibaba in 2017.
