At the end of 1990, Vladimir Vapnik moved to the
USA and joined the Adaptive Systems Research Department at
AT&T Bell Labs in
Holmdel, New Jersey. While at AT&T, Vapnik and his colleagues did work on the
support-vector machine (SVM), which he also worked on much earlier before moving to the USA. They demonstrated its performance on a number of problems of interest to the
machine learning community, including
handwriting recognition. The group later became the Image Processing Research Department of
AT&T Laboratories when AT&T spun off
Lucent Technologies in 1996. In 2001,
Asa Ben-Hur,
David Horn,
Hava Siegelmann and Vapnik developed Support-Vector Clustering, which enabled the algorithm to categorize inputs without labels—becoming one of the most ubiquitous data clustering applications in use. Vapnik left AT&T in 2002 and joined
NEC Laboratories in
Princeton, New Jersey, where he worked in the Machine Learning group. He also holds a Professor of Computer Science and Statistics position at
Royal Holloway, University of London since 1995, as well as a position as Professor of Computer Science at
Columbia University,
New York City since 2003. As of February 1, 2021, he has an
h-index of 86 and, overall, his publications have been cited 226597 times. His book on "The Nature of Statistical Learning Theory" alone has been cited around 113000 times. On November 25, 2014, Vapnik joined Facebook Artificial Intelligence Research (now
Meta AI), where he is working alongside his longtime collaborators Jason Weston,
Léon Bottou, Ronan Collobert, and
Yann LeCun. In 2016, he also joined
Peraton Labs. ==Honors and awards==
