Talk Title: Structured Prediction

Talk Abstract:
Struct

ured prediction is a framework for solving problems of
classification or
regression in which the output variables are
mutually dependent or cons

trained. These dependencies and
constraints reflect sequential spatial

or combinatorial structure
in the problem domain and capturing such in

teractions is often
as important as capturing input-output dependencies

. Many such
problems including natural language parsing machine trans

lation
object segmentation gene prediction protein alignment and num

erous
other tasks in computational linguistics speech vision biology
are not
new. However recent advances have brought about a unified vie

w
efficient methodology and more importantly significant accuracy

improvements for both classical and novel problems. I will outline the
f

undamental computational and statistical methods and challenges in
struc

tured prediction.
