Abstract

In this talk, coding and testing schemes for hypothesis testing over multi-hop networks are presented. The schemes are based on unanimous decision forwarding where the terminals decide on the null hypothesis if all previous terminals have decided on this hypothesis and they forward their decisions to the next terminal. The proposed coding and testing schemes are shown to achieve the optimal type-II error exponent region for some special cases of testing against independence. The proposed schemes are further improved by means of binning. The improved schemes are analyzed using Han’s approach and shown to be optimal for a special case of testing against conditional independence. An extension of this analysis to hypothesis testing over a noisy channel is also discussed.

Bio: Sadaf Salehkalaibar received the B.Sc., M.Sc. and Ph.D. degrees in Electrical Engineering from Sharif University of Technology, Tehran, Iran in 2008, 2010 and 2014, respectively. She was a postdoctoral fellow at Telecom ParisTech, Paris, France in 2015 and 2017. She is currently an assistant professor at Electrical and Computer Engineering Department of University of Tehran. Her special fields of interest include network information theory, hypothesis testing and fundamental limits of secure communication with emphasis on information-theoretic security.
