Deep learning is a growing scientific research trend in machine learning and artificial intelligence due to its better performance compared to other machine learning techniques. The presented computer-aided diagnosis system can act as an assistive tool to confirm the finding of PD for the clinicians. They demonstrate that using the support vector machines (SVM) classifier, the feature ranking, and the principal component analysis technique, the proposed system can detect the PD signals automatically with maximum accuracy of 99.1% ± 0.1%.
