A Variational Characterization of $H$ -Mutual Information and its Application to Computing $H$ -Capacity

Akira Kamatsuka, Koki Kazama, Takahiro Yoshida

$H$ -mutual information ( $H$ -MI) is a wide class of information leakage measures, where $H = (η, F)$ is a pair of monotonically increasing function $η$ and a concave function $F$ , whi…

On Hypothesis Testing via a Tunable Loss

Akira Kamatsuka

We consider a problem of simple hypothesis testing using a randomized test via a tunable loss function proposed by Liao \textit{et al}. In this problem, we derive results that corr…
