Vanishing Component Analysis with Contrastive Normalization
Ryosuke Masuya, Yuichi Ike, Hiroshi Kera
Vanishing component analysis (VCA) computes approximate generators of vanishing ideals of samples, which are further used for extracting nonlinear features of the samples. Recent s…

The geometry of three sections on certain rational elliptic surfaces and Mumford representations
Ryosuke Masuya
In this article, we study the geometry of plane curves obtained by three sections and another section given as their sum on certain rational elliptic surfaces. We make use of Mumfo…

Trisections on Certain Rational Elliptic Surfaces and Families of Zariski Pairs Degenerating to the same Conic-line Arrangement
S. Bannai, N. Kawana, R. Masuya +1
In this paper, we study the geometry of trisections on certain rational elliptic surfaces. We utilize Mumford representations of semi-reduced divisors in order to construct trisect…
