Comparison of the prediction power among DRSF model with 5 windows, Penalized Cox regression model with most recent window (1 window), and the batch-mode RSF model using the testing window from March 1st, 2015 to August 31st, 2015. The black line is the AUC curve of DRSF with 5 windows, the red line is the AUC curve of Penalized Cox regression with 1 window, and the green line is the AUC curve of batch-mode RSF model. The x-axis represents the number of days since March 1st, 2015. The y-axis represents the Area-Under-the-ROC-Curve (AUC)
