Abstract(in English) | Coherent phonon (CP) signals contain normal modes representing the material property and experimental artifacts. It is possible to rate the signals into each damped oscillation by dynamic mode decomposition (DMD). In order to know the material properties, it is necessary to extract only meaningful signals from the decomposed components (mode selection). In recent years, Murata et al. proposed a extraction method based on the magnitude of experimental known noise. In this research, we propose a framework of mode selection without using experimental noise which is difficult to measure. After estimating the candidate oscillation modes, we select candidate combinations in the framework of Bayesian free energy minimization. |
