Léon Bottou (French pronunciation: [leɔ̃ bɔtu]; born 1965) is a researcher best known for his work in machine learning and data compression.
He then joined the Adaptive Systems Research Department at AT&T Bell Laboratories in Holmdel, New Jersey, where he collaborated with Vladimir Vapnik on local learning algorithms.
[2] in 1992, he returned to France and founded Neuristique S.A., a company that produced machine learning tools and one of the first data mining software packages.
In 1995, he returned to Bell Laboratories, where he developed a number of new machine learning methods, such as Graph Transformer Networks (similar to conditional random field), and applied them to handwriting recognition and OCR.
In 1996, he joined AT&T Labs and worked primarily on the DjVu image compression technology,[4] that is used by some websites, notably the Internet Archive, to distribute scanned documents.
