Learning Sign-Constrained Support Vector Machines

no code implementations5 Jan 2021 Kenya Tajima, Takahiko Henmi, Kohei Tsuchida, Esmeraldo Ronnie R. Zara, Tsuyoshi Kato

One of the two algorithms is based on the projected gradient method, in which each iteration of the projected gradient method takes $O(nd)$ computational cost and the sublinear convergence of the objective error is guaranteed.

Adaptive Signal Variances: CNN Initialization Through Modern Architectures

no code implementations16 Aug 2020 Takahiko Henmi, Esmeraldo Ronnie Rey Zara, Yoshihiro Hirohashi, Tsuyoshi Kato

In this study, we derived the initialization scheme again not from the simplified Kaiming model, but precisely from the modern CNN architectures, and empirically investigated how the new initialization method performs compared to the de facto standard ones that are widely used today.
