Chih-Jen Lin (Chinese: 林智仁; pinyin: Lín Zhìrén) 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.[2] With his students he also developed LIBLINEAR, a widely used library for large-scale linear classification.[3]

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.[4][5]

Lin's machine-learning software has been adopted by industry, with his libraries used by Yahoo, Google, eBay, and Microsoft.[6] He has held visiting research positions, as a visiting scientist at Yahoo! Research (2006–2007) and visiting professor at Google Research (2008),[4] and as a visiting scholar at Alibaba in 2017.[7]

Awards and honors

  • ACM Fellow (2015), for contributions to the theory and practice of machine learning and data mining[8]
  • TECO Award (2015) in Electrical Engineering, Information and Communication Technology[1]
  • AAAI Fellow (2014), for contributions to machine learning and the development of widely used SVM software; he was the first researcher from Taiwan to be elected an AAAI Fellow[9][4][10]
  • Best Paper Award (2013), ACM Conference on Recommender Systems[11]
  • IEEE Fellow (2011), for contributions to support vector machine algorithms and software[4]
