| Outline of Final Research Achievements |
Resting potentials of needle electromyography (needle EMG) obtained from patients with neuromuscular diseases were databased. The classified waveforms were divided into 2-second audio files. Method 1) Audio characteristics were obtained from each audio file. Machine learning methods was used to classify the six resting potentials. The accuracy was 90.4%. Method 2) The same database as the method 1 was used. The audio information was transformed into melspectrogram as image files. The images were divided into training and test data. The training data were then trained with convolutional neural networks (CNNs). Image augmentation was useful in that the accuracy was 100%.

| Academic Significance and Societal Importance of the Research Achievements |
針筋電図の放電判別は専門医以外には容易ではなく、正確な診断を妨げている。本研究により機械学習やディープラーニングを用いることで高精度に判別が可能であることが分かった。今後は実用化に向けて対象となる波形を増やしていく。
