Abstract (in Japanese) (See Japanese page) 
(in English) In non-contact respiratory measurement using radar, estimation accuracy can decrease depending on the subject's posture and body orientation. Therefore, it is important to evaluate the accuracy in estimating the respiratory motion. This study proposes a machine-learning-based method for predicting estimation accuracy directly from radar signals. To efficiently generate training data under diverse measurement conditions, radar signals are simulated using human body models reconstructed from depth-camera measurements. In addition, recurrence plots are used as the input for the machine learning model. Compared with the conventional method using spectrograms as input, the proposed method improved the correlation coefficient between the actual and predicted values by an average of 3.64% and reduced the root-mean-square error by an average of 3.27%.
