a PR (left) and ROC (right) curves for model distinguishing between self-isolation and hospitalization outcomes. Each colored line represents a separate model and the color scheme is consistent between PR and ROC curves. Feature importance from (b) early fusion—shows the importance of top 25 individual EMR data component, c late Fusion model—shows the importance of individual EMR data sources. The standard deviation bar (red) is generated via 10-fold cross-validation on the training data. d Calibration curve for early, late and middle fusion models along with Brier scores for each calibrated model.
