Autor: Nagai, Tomoko, Okuda, Takayuki, Nakamura, Tomoya, Sato, Yuichiro, Sato, Yusuke, Kinjo, Kensaku, Kawamura, Kengo, Kikuta, Shin, Kumano-go, Naoto

This study examines the educational effect of the Academic Support Center at Kogakuin University. Following the initial assessment, it was suggested that group bias had led to an underestimation of the Center's true impact. To address this issue, the

On a parametrized difference equation connecting chaotic and integrable mappings

Autor: Nagai, Tomoko, Nagai, Atsushi, Yamaki, Hiroko, Yanuma, Kana

We present a new difference equation with two parameters c in [0,1] and A in [1,4]. This equation is equivalent to the logistic mapping if c=1 and the Morishita mapping if c=0, which are the well-known chaotic and integrable mappings, respectively. W

The covariance matrix of Green's functions and its application to machine learning

Autor: Nagai, Tomoko

In this paper, a regression algorithm based on Green's function theory is proposed and implemented. We first survey Green's function for the Dirichlet boundary value problem of 2nd order linear ordinary differential equation, which is a reproducing k
