Voice2Series (V2S) is proposed, a novel end-to-end approach that reprograms acoustic models for time series classification, through input transformation learning and output label mapping and it is shown that V2S performs competitive results on 19 time series Classification tasks.
The proposing solution is to use deep learning architectures where first layers of convolutional neurons behave as feature extractors and in the end some fully-connected (FCN) layers are used for making final decision about ECG classes.
A deep convolutional neural network was trained to classify single lead ECG waveforms as either Normal Sinus Rhythm, Atrial Fibrillation, or Other Rhythm, and class activation mappings were extracted to help better understand which areas of the waveform the model was focusing on when making a classification.
The TMF classification model has very good clinical interpretability and the patterns revealed by symmetrized Gradient-weighted Class Activation Mapping have a clear clinical interpretation at the beat and rhythm levels.
An ECG signal classification method based on the images is presented to classify ECG signals into normal and abnormal beats by using two-dimensional convolutional neural networks (2D-CNNs) to alleviate the overfitting problem in two- dimensional network.
Results indicate ECG analysis based on DNNs, previously studied in a single-lead setup, generalizes well to 12-lead exams, taking the technology closer to the standard clinical practice.
A CNN is designed for classification of 12-lead ECG signals with variable length, and three defense methods are applied to improve robustness of this CNN against adversarial noises and white noises, with a minimal reduction in accuracy on clean data.
The proposed algorithm has advantages of high reconstruction performance for BOW, this storage method is high fidelity and low memory consumption; on the other hand, the algorithm yields highest accuracy in ECG beats classification; so this method is more suitable for large-scale heart beats data storage and classification.
Adding a benchmark result helps the community track progress.
