Abstract:Sleep apnea is a common sleep disorder. To address the characteristics of ECG signals, we introduce a coordinate attention mechanism and propose an automatic sleep apnea classification model (CA-EfficientNet) based on wavelet transform and lightweight neural network. One-dimensional signals were converted into two-dimensional images by wavelet transform and in put into the proposed model for classification. The effects of input time window, wavelet transform type and data balance on classification performance … Show more
