“…As said, use of ECG features instead of raw data (as sometimes done when using long short-term memory, 1D convolutional neural network and others [ 11 , 15 , 16 , 33 , 34 ]) at the input of RSL_ANN implies adding an ECG processing step for feature extraction before classification; however, it also allows the construction of a faster and simpler artificial neural network, since based on a reduced number of hidden layers, through a smaller training dataset. In addition, since each feature, if well selected, reflects a specific physiologic phenomenon, classification logic of a network is physiologically more understandable than when it is based on raw data, and this is very much appreciated in context in which interpretability of the model is desirable.…”
