Relative Density-Ratio Estimation for Robust Distribution Comparison
Makoto Yamada, Taiji Suzuki, Takafumi Kanamori +2
Divergence estimators based on direct approximation of density-ratios without going through separate approximation of numerator and denominator densities have been successfully app…

A Bregman Extension of quasi-Newton updates I: An Information Geometrical framework
Takafumi Kanamori, Atsumi Ohara
We study quasi-Newton methods from the viewpoint of information geometry induced associated with Bregman divergences. Fletcher has studied a variational problem which derives the a…

A Bregman Extension of quasi-Newton updates II: Convergence and Robustness Properties
Takafumi Kanamori, Atsumi Ohara
We propose an extension of quasi-Newton methods, and investigate the convergence and the robustness properties of the proposed update formulae for the approximate Hessian matrix. F…
