Computation of the Gradient and the Hessian of the Log-likelihood of the State-space Model by the Kalman Filter
G. Kitagawa
The maximum likelihood estimates of an ARMA model can be obtained by the Kalman filter based on the state-space representation of the model. This paper presents an algorithm for co…
Complete Multipole Basis Set for Single-Centered Electron Systems
Hiroaki Kusunose, Rikuto Oiwa, Satoru Hayami
A whole series of expressions for four species of multipoles (electric, magnetic, magnetic toroidal, and electric toroidal) is provided as a complete basis set to describe arbitrar…
Cubical Ripser: Software for computing persistent homology of image and volume data
Shizuo Kaji, Takeki Sudo, Kazushi Ahara
We introduce Cubical Ripser for computing persistent homology of image and volume data (more precisely, weighted cubical complexes). To our best knowledge, Cubical Ripser is curren…
PJS: phoneme-balanced Japanese singing voice corpus
Junya Koguchi, Shinnosuke Takamichi
This paper presents a free Japanese singing voice corpus that can be used for highly applicable and reproducible singing voice synthesis research. A singing voice corpus helps deve…
Construction of strictly closed rings
Naoki Endo, Shiro Goto
The notion of strict closedness of rings was given by J. Lipman in connection with a conjecture of O. Zariski. The present purpose is to give a practical method of construction of…
Localized and Expanding Entire Solutions of Reaction-Diffusion Equations
F. Hamel, H Ninomiya
This paper is concerned with the spatio-temporal dynamics of nonnegative bounded entire solutions of some reaction-diffusion equations in R N in any space dimension N. The solution…
