Feature reduction method using self organizing maps

Abstract

In this work, five main groups of arrhythmias in electrocardiograph (ECG) signals are tried to be classified using the features obtained from the output of a Self Organizing Map (SOM) network. The raw ECG signal consists of 81 sample points (60 point before and 20 point after the R peak point of the ECG). Consecutive sample values of a moving window (20… (More)
