'''Leo Breiman''' (January 27, 1928 – July 5, 2005) was an American [[statistician]] at the [[University of California, Berkeley]] and a member of the [[United States National Academy of Sciences]].

Breiman's work helped to bridge the gap between statistics and [[computer science]], particularly in the field of [[machine learning]]. His most important contributions were his work on [[decision tree learning|classification and regression trees]] and ensembles of trees fit to [[bootstrap (statistics)|bootstrap]] samples. [[Bootstrap aggregating|Bootstrap aggregation]] was given the name [[bootstrap aggregating|''bagging'']] by Breiman. Another of Breiman's ensemble approaches is the [[random forest]].
