Does a deep representation learning method with a novel re-sampling strategy and augmented attention module improve heartbeat classification performance for arrhythmia detection in imbalanced ECG data?
A novel deep representation learning method with a unique re-sampling strategy and augmented attention module improves the classification of arrhythmic beats in imbalanced ECG datasets.
Developing an efficient heartbeat monitoring system has become a focal point in numerous healthcare applications. Specifically, in the last few years, heartbeat classification for arrhythmia detection has gained considerable interest from researchers. This paper presents a novel deep representation learning method for the efficient detection of arrhythmic beats. To mitigate the issues associated with the imbalanced data distribution, a novel re-sampling strategy is introduced. Unlike the existing oversampling methods, the proposed technique transforms majority-class samples into minority-class samples with a novel translation loss function. This approach assists the model in learning a more generalized representation of crucially important minority class samples. Moreover, by exploiting an auxiliary feature, an augmented attention module is designed that focuses on the most relevant and target-specific information. We adopted an inter-patient classification paradigm to evaluate the proposed method. The experimental results of this study on the MIT-BIH arrhythmia database clearly indicate that the proposed model with augmented attention mechanism and over-sampling strategy significantly learns a balanced deep representation and improves the classification performance of vital heartbeats.
Zubair et al. (Wed,) conducted a other in Arrhythmia detection (n=100,693). Deep learning model with augmented attention module and oversampling strategy vs. Conventional model without attention and oversampling was evaluated on Classification accuracy, sensitivity, specificity, and positive productivity for arrhythmia detection. The deep learning model with augmented attention and oversampling strategy achieved a classification accuracy of 96.19% for detecting arrhythmia beats compared to conventional models.
