1. An integrated biosignal analysis system performing determination of arrhythmia based on electrocardiographic information, the biosignal analysis system comprising:
an input unit configured to receive input of the electrocardiographic information;
a data conversion unit configured to perform time-frequency conversion on the electrocardiographic information to generate data for determination;
a data restoration unit configured to restore the data for determination using a learned model including an auto-encoder to generate restored data;
a difference calculation unit configured to calculate a difference amount between the restored data and the data for determination; and
a determination unit configured to determine whether the data for determination is either of normal waveform data and arrhythmic waveform data based on the difference amount.
