Abstract: | In the classification system for longtime and massive ECG signals, ECG diagnosis is time-consuming, laborious and costly. It is difficult to extract signal features because of the complex ECG morphology. The diagnosis model has low adaptability and accuracy. To solve the above problem, a novel method for ECG classification using deep learning and fuzzy C-means is proposed. The method includes four steps:ECG signal preprocessing, heartbeat segmentation and sampling point unification, ECG feature deep learning, fuzzy C-means classification. The structure and algorithm of fuzzy C-means deep belief networks (FCMDBN) are shown in the paper. The method is validated on the well-known MIT-BIH arrhythmia database. Experiment results show that the approach achieves higher adaptability and accuracy than traditional hand-designed methods on classification of ECG signals. |
