Abstract
A physiological information acquisition device configured to acquire physiological information of a subject includes: an input interface configured to receive waveform data corresponding to a measurement waveform of the physiological information from a sensor; a prediction unit configured to extract a feature from the waveform data using a convolutional neural network and predict a probability of the waveform data being classified into each of a plurality of classes; an importance specification unit configured to specify an importance of the feature with respect to a prediction result of the probability for at least one of the plurality of classes; and an output unit configured to output an indicator indicating the importance together with the measurement waveform.
