| Abstract(in English) | Estimation of latent dynamics from time-series data is important problem in a broad range of fields. In this research, we focused on time-series spectral data, which is obtained in planetary science, condensed matter science or any other field, and its latent dynamics. Center, width and amplitude of each peak reflect the nature of subject. In this research, we proposed a method to estimate the parameters and their latent dynamics, and the number of peaks and the order of the model by using Bayesian inference. |
