Mehryar Mohri is a professor of computer science
at the Courant Institute of Mathematical Sciences
at New York University
known for his work in machine learning
, automata theory
and algorithms, speech recognition
and natural language processing
.
He received his B.S from Ecole Polytechnique
(1987), his M.S. in computer science and applied mathematics from École Normale Supérieure
(1989) and his Ph.D. in 1993 from the University of Paris 7 Denis Diderot. Prior to joining the Courant Institute in 2004, Mohri worked for ten years at Bell Labs
and AT&T Labs
, where he was Head of the Speech Algorithms Department.
Mohri's main areas of research are machine learning
, theory, computational biology
,
and text and speech processing
. He is
the author of many core weighted automata and finite state transducer
algorithms and pioneered the application of weighted finite state transducer
s (WFSTs) to speech recognition
and natural language processing
with his colleagues at AT&T.
At the Eurospeech 2001 conference in Aalborg
, a paper by Mohri and Michael Riley, “Network Optimizations for Large-Vocabulary Speech Recognition,” was given an award by the International Speech Communication Association as “the best paper published in Speech Communications during 1998-2000.” His work with Brian Roark, “Probabilistic Context-Free Grammar Induction Based on Structural Zeros,” won a best paper award at HLT-NAACL 2006. Mohri is Editorial Board member of Machine Learning
and member of the advisory board for the Journal of Automata, Languages and Combinatorics
