Supervised machine learning methods were applied to construct the CBIT. Temporal information about times from the first and the most recent occurrence of diagnoses was encoded. Ten-fold cross-validation was used to tune hyperparameters, and independent test sets were used to evaluate models using AUC, accuracy, recall and precision. Random forest achieved the best model quality. Models were calibrated using isotonic regression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The unabridged version of CBIT uses 578 patient characteristics and achieved average AUC of 0.94 (0.93\u20130.95), accuracy of 0.90 (0.89\u20130.91), precision of 0.91 (0.89\u20130.92), and recall of 0.90 (0.84\u20130.95) when re-evaluating patients. CBIT is also capable of predicting ADLs up to one year ahead, with accuracy decreasing over time, giving average AUC of 0.77 (0.73\u20130.79), accuracy of 0.73 (0.69\u20130.80), precision of 0.74 (0.66\u20130.81), and recall of 0.69 (0.34\u20130.96).
