Distributed Hypothesis Testing Against Dependence
Han Wu, Shun Watanabe
We study distributed hypothesis testing and establish the exact error exponent in single-letter form for new testing problems. In distributed hypothesis testing, a receiver decides…
On The Most Discriminative Boolean Functions for Correlated Sources
Jun Chen, Shun Watanabe, Lei Yu
Motivated by a conjecture of Amari and Kobayashi, we study the problem of identifying pairs of Boolean functions that maximize the Kullback-Leibler divergence between two distribut…
UMVUE-Type Estimators under Bregman Losses
Akira Kamatsuka, Shun Watanabe
We study unbiased estimation under Bregman losses and develop an extension of the classical theory of uniformly minimum variance unbiased estimators (UMVUEs). Exploiting bias--vari…
A Geometric Reduction Approach for Identity Testing of Reversible Markov Chains
Geoffrey Wolfer, Shun Watanabe
We consider the problem of testing the identity of a reversible Markov chain against a reference from a single trajectory of observations. Employing the recently introduced notion…
Tight Exponential Strong Converse for Source Coding Problem with Encoded Side Information
Daisuke Takeuchi, Shun Watanabe
The source coding problem with encoded side information is considered. A lower bound on the strong converse exponent has been derived by Oohama, but its tightness has not been clar…
On Sub-optimality of Random Binning for Distributed Hypothesis Testing
Shun Watanabe
We investigate the quantize and binning scheme, known as the Shimokawa-Han-Amari (SHA) scheme, for the distributed hypothesis testing. We develop tools to evaluate the critical rat…
