Jerome Friedman, Stanford Professor of Statistics and member of SLAC Computing Services, is the winner of the 2004 Parzen Prize, established by Emanuel and Carol Parzen to "record the contemporary history of statistical innovation."  Friedman has created many new statistical methods used widely today in exploratory data analysis -- searching for patterns in unstructured data -- and in "machine learning" -- teaching computers to make decisions in problems where humans excel.  His work has been applied in fields ranging from computer vision to medical diagnosis to financial portfolio management.  He received the award March 1 at Texas A&M University.
