Speed-Up Method for Optimal Quantizations of Binary-Input Discrete Memoryless Channels with Monge Property
Yuta Sakai, Ken-ichi Iwata (Univ. of Fukui) IT2016-40
Abstract (in Japanese) (See Japanese page) 
(in English) This study examines quantizations for outputs of binary-input discrete memoryless channels (B-DMCs) by concatenating a DMC, so-called a quantizer, to the output of the B-DMC.
In this study, we define a generalized information measures for B-DMCs, which contains the mutual information, Gallager's reliability function $E_{0}$, the $alpha$-mutual information, and the $f$-divergence.
We call such generalized information measures the $phi$-information, and we evaluate
the loss of quantizations by using the $phi$-information.
The main result of this study is to reduce the computational complexity for finding an optimal quantizer by using the Monge property.
