• Abstract summary: New methods for time-to-event prediction have been developed by extending the cox-proportional hazards model with neural networks. We generate simulated survival datasets based on the expert annotated ejection fraction readings. By training on just the simulated survival outcomes, we show thattemporal convolutional neural networks yield accurate survival estimates.

• Abstract: Integrating methods for time-to-event prediction with diagnostic imaging modalities is of considerable interest, as accurate estimates of survival requires accounting for censoring of individuals within the observation period. New methods for time-to-event prediction have been developed by extending the cox-proportional hazards model with neural networks. In this paper, to explore the feasibility of these methods when applied to deep learning with echocardiography videos, we utilize the Stanford EchoNet-Dynamic dataset with over 10,000 echocardiograms, and generate simulated survival datasets based on the expert annotated ejection fraction readings. By training on just the simulated survival outcomes, we show that spatiotemporal convolutional neural networks yield accurate survival estimates.

  Supervised deep learning has been widely used in the studies of automatic ECG classification. Most of the existing large ECG datasets are roughly annotated, so the classification model trained on them can only detect the existence of abnormalities in a whole recording. This study proposes weakly supervised deep learning models for detecting abnormal ECG events and their occurrence time.
