John Carlton Platt (born 1963) is an American Principal Scientist at Google. Formerly he was a Deputy Managing Director at Microsoft Research Redmond Labs. Platt worked for Microsoft from 1997-2015. Prior to Microsoft, Platt had served as Director of Research at Synaptics.

Life and work

Platt was born in Elgin, Illinois and matriculated at California State University, Long Beach at the age of 14. After graduating from CSULB at the age of 18, Platt enrolled in a computer science PhD program at California Institute of Technology.

While a student at Caltech under astronomer Gene Shoemaker, Platt discovered two asteroids, one of which he named after his father (3237 Victorplatt).

In August 2005, Apple Computer had its application for a patent on the interface of the popular iPod music player rejected by the United States Patent and Trademark Office. The reason appears to be that Platt had submitted a patent application for a similar interface design five months prior to Apple's claim.

Platt shared a 2005 Scientific and Technical Achievement Oscar from the Academy of Motion Picture Arts and Sciences with Demetri Terzopoulos for their pioneering work in physically based computer-generated techniques used to simulate realistic cloth in motion pictures.

Platt invented Sequential minimal optimization, a widely used method for training support vector machines, as well as Platt scaling, a method to turn SVMs (and other classifiers) into probability models.
