Title : Decentralized detection: tractability through asymptotics
Date : October 6, 2006. (2:00 pm) Tea starts half an hour before each seminar
Location: ITEB 336
Speaker : Prof. John Tsitsiklis
Abstract:
We discuss issues related to decentralized detection
in a system comprised by distributed sensors. While
many approaches to the problem are intractable,
considerable simplifications are possible in the
limit of a large number of sensors. After some brief
history and background, we discuss an example
involving optimal censoring in the presence of side
information. We then address some architectural
questions and compare the performance of different
tree architectures. Somewhat surprisingly, we show
that under certain assumptions, a tree architecture
performs as well as a star configuration. (Joint
work with Wee Peng Tay and Moe Win.)
