Key result
A novel approach using independent component analysis, wavelet transform, and multilayer neural networks achieved 98.5% accuracy in detecting and classifying cardiac arrhythmias.
A novel machine learning approach using ICA and wavelet transform achieved high accuracy (98.5%) in detecting and classifying cardiac arrhythmias from ECG signals.
Requires prospective validation before clinical use; extends prior ML methods but leaves real-world adoption open.
In this paper a novel approach for cardiac arrhythmias detection is proposed. The proposed method is based on using independent component analysis (ICA) and wavelet transform to extract important features. Using the extracted features different machine learning classification schemas, MLP and RBF neural networks and K-nearest neighbor, are used to classify 274 instance signals from the MIT-BIH database. Simulations show that multilayer neural networks with Levenberg-Marquardt (LM) back propagation algorithm provide the optimal learning system. We were able to obtain 98.5% accuracy, which is an improvement in comparison with the similar works.
