It may indicate the presence of heart disorders and provide clinical information in the diagnostic process. In this study, a novel feature dimension reduction method based on independent component analysis (ICA) has been proposed for the classification of fourteen different heart sound types; the method was compared with principal component analysis. The feature vectors are classified by support vector machines, linear discriminant analysis, and naive Bayes (NB) classifiers using 10 -fold cross validation. The ICA combined with NB achieves the highest average performance with a sensitivity of 98.53%, specificity of 99.89%, g -means of 99.21%, and accuracy of 99.79%.EnglishHIDDEN MARKOV MODELWAVELET TRANSFORMPCADIAGNOSISSYSTEMICALDAALGORITHMSDISEASEHeart sound signal classification using fast independent component analysisArticle
