| Abstract(in English) | This paper described a frequency analysis of bio-vibration data obtained from mat sensor with sleep apnea syndrome (SAS) subjects and non-SAS subjects based on the differences. The differences were discovered through the comparison of the feature importance of each frequency calculated from Random Forests trained with the power spectrum of bio-vibration data during WAKE (shallow sleep) and non-WAKE. From the result, the following implications have been revealed: the bio-vibration data during WAKE show that (1) the density of the power spectrum at the time of WAKE is generally larger in non-SAS subjects because of the WAKE with large body movements, and (2) SAS subjects have the tendency to increase the density of the power spectrum around 0.3Hz, which may be a disruption of breathing due to the disturbance of the autonomic nervous system caused by apnea/hypopnea. Based on future findings, we can expect to use this as the novel indicator of SAS. |
