Subasi A (2013) Classification of EMG signals using PSO optimized SVM for diagnosis of neuromuscular disorders. Comput Biol Med 43(5):576–586. Since an SVM is essentially a binary classifier, a one-layer SVM model can only classify two kinds of operation conditions of HVCBs. For the classification of a normal condition mechanism fault and four types of operating mechanism faults, a four-layer SVM classifier shown in Figure 6is constituted as the fault … See more Based on statistical theory, a novel learning algorithm named SVM was proposed by Vapnik and co-authors in the late 1990s [30]. The … See more The kernel parameter δ and error penalty c are significant for the classification accuracy of the SVM model. Thus, they are predetermined by the PSO algorithm in the study. The basic idea of the PSO algorithm is that the … See more
