CEFEs: A CNN Explainable Framework for ECG Signals

作者:

Highlights:

• Interpretable explanations by means of functional understanding of internal mechanism of 1D-CNNs for ECG decision support systems, addressing the trust gap found in deep learning.

• Interpretable explanations as metrics that evaluate the quality of CNN models through a set of tri-fold modular tests: a) descriptive statistics, b) visualization and c) detection and mapping of input ECG signal in comparison to its learned feature maps.

• Benchmark for interpretable explanation-based evaluation of CNN models trained for ECG signal classification task.

• Understanding the relationships between machine learned features and the features’ contributions to misclassification of target classes.

• Comparative analysis of machine learned class discriminant features and actual ECG observable diagnostic waveform features.
