A transformer network is embedded in the CNN framework for the identification of ECG signals. The integration of the transformer compensates for the shortcomings of the CNN for poor performance of temporal features. A new link constraint is introduced in the loss function. In the previous schemes...
promising recently proposed transformer-based architectures – can also be alternative solutions when a high number of unlabeled data are available. They can be exploited to learn data properties and extract representative features that can be used to solve classification tasks with less data. However,...
