Embodiment Construction

[0037] The present invention will be described in further detail below with reference to the embodiments, which are to explain rather than limit the present invention.

[0038] see Figure 1-Figure 3 , Figure 5 , the method for identifying ECG signals based on the DWNN framework provided by the present invention includes the following operations:

[0039] 1) Construct a DWNN framework model including a deep feature construction module, a fully connected layer and an output layer, in which the deep feature extraction module includes n sub-modules composed of wavelet layers and pooling layers, and the ECG signal alternately enters the wavelet layer and the pooling layer. The wavelet layer extracts the deep data features in the ECG signal through wavelet decomposition and random weighted reconstruction, and the pooling layer performs pooling and dimension reduction on the extracted deep data features, and after alternate processing, the deep features of the wavelet structure ar...

Abstract

The invention discloses a method for recognizing electrocardiogram signals based on a DWNN framework. The electrocardiogram enters the wavelet layer as the original data, and the wavelet layer extracts deep data features in the electrocardiogram through wavelet decomposition and random weighting reconstruction, and the pooling layer pairs extract The obtained data features are reduced in dimension through pooling operation. The fully connected layer combines the reduced data features, and the output layer uses the softmax function to output the classification results. Among the 800 test ECG signals, the present invention predicts 794 signals correctly and 6 signals incorrectly, and the prediction accuracy rate of the present invention is 99.25%. The result shows that the present invention has more obvious classification recognition results.
