• Signal Processing

Background:

• Existing deep learning methods for ECG classification struggle with patient-specific data scarcity and real-time performance.
• Conventional 1D Convolutional Neural Networks (CNNs) have limitations due to their homogenous structure and basic neuron models, hindering optimal learning.
• Accurate patient-specific ECG analysis is crucial for timely arrhythmia detection and management.

Purpose of the Study:

• Comparison of 1D Self-ONN performance against established 1D CNN models.

Main Results:

• 1D Self-ONNs achieved 98% and 99.04% average accuracies on the MIT-BIH dataset.
• Exceptional average F1 scores of 76.6% and 93.7% for supra-ventricular and ventricular ectopic beat classifications, respectively.
• The proposed 1D Self-ONNs demonstrated superior performance over 1D CNNs with comparable computational complexity.

Conclusions:

• 1D Self-ONNs represent a significant advancement in patient-specific ECG classification, outperforming existing methods.
