Analysis of multiple data sequences with different distributions: defining common principal component axes by ergodic sequence generation and multiple reweighting composition
Ikuo Fukuda, Kei Moritsugu
Principal component analysis (PCA) defines a reduced space described by PC axes for a given multidimensional-data sequence to capture the variations of the data. In practice, we ne…

On ergodicity for multi-dimensional harmonic oscillator systems with Nose-Hoover type thermostat
Ikuo Fukuda, Kei Moritsugu, Yoshifumi Fukunishi
A simple proof and detailed analysis on the non-ergodicity for multidimensional harmonic oscillator systems with Nose-Hoover type thermostat are given. The origin of the nonergodic…
