SEVGGNet-LSTM: a fused deep learning model for ECG classification
This is an incremental improvement for medical ECG analysis, potentially aiding in automated diagnosis.
The paper tackled ECG classification by fusing VGG and LSTM networks with an attention mechanism, achieving effective and robust results validated on two databases.
This paper presents a fused deep learning algorithm for ECG classification. It takes advantages of the combined convolutional and recurrent neural network for ECG classification, and the weight allocation capability of attention mechanism. The input ECG signals are firstly segmented and normalized, and then fed into the combined VGG and LSTM network for feature extraction and classification. An attention mechanism (SE block) is embedded into the core network for increasing the weight of important features. Two databases from different sources and devices are employed for performance validation, and the results well demonstrate the effectiveness and robustness of the proposed algorithm.
