• Sparse kernel canonical correlation analysis for discovery of nonlinear interactions in high-dimensional data

Yoshida Kosuke , Yoshimoto Junichiro , Doya Kenji

Canonical correlation analysis (CCA) is a statistical tool for finding linear associations between different types of information. … Previous extensions of CCA used to capture nonlinear associations, such as kernel CCA, did not allow feature selection or capturing of multiple canonical components. … Using artificial datasets and nutrigenomic datasets, we show that TSKCCA can extract multiple, nonlinear associations among high-dimensional data and multiplicative interactions among variables. …

• Extracting nuclear sizes of medium to heavy nuclei from total reaction cross sections

Horiuchi W. , Hatakeyama S. , Ebata S. , Suzuki Y.

… To substantiate the treatment of the Coulomb breakup, we also evaluate the Coulomb breakup cross section due to the electric dipole field in a canonical-basis-time-dependent-Hartree-Fock-Bogoliubov theory in the three-dimensional coordinate space. … We find that the so-called reaction radius, sigma(R) = root sigma(R)/pi, for the proton target is very well approximated by a linear function of two variables, the matter radius and the skin thickness, in which three constants depend only on the incident energy. …
