A recurrent neural network approach for remaining useful life prediction utilizing a novel trend features construction method

The invention belongs to field of electrocardiogram atrial fibrillation prediction, and particularly discloses an atrial fibrillation prediction device and equipment based on deep learning. The devicecomprises an information extraction module, an information processing module and a result prediction module. The information extraction module is used for acquiring multi-lead original electrocardiogram data and obtaining electrocardiogram rhythm information corresponding to leads; the information processing module is used for determining R point positions in the electrocardiogram rhythm information, heartbeat cycles corresponding to the R point positions and waveform information of the heartbeat cycles by adopting a filter so as to construct waveform information sets. Feature extraction anddimensionality reduction are performed on the waveform information set corresponding to each heartbeat period by using a noise reduction autoencoder, multi-dimensional feature data corresponding to the waveform information set are obtained, and mean value and variance of feature data of each dimension are calculated. The result prediction module is used for comparing the mean value and the variance of the multi-dimensional feature data corresponding to different heartbeat periods with the adaptive threshold of the heartbeat period according to the time sequence, and judging whether atrial fibrillation occurs in the heartbeat period or not. The accuracy of atrial fibrillation prediction is improved.
