ABSTRACT
Objective To explore the prediction efficiency of multilayer perception (MLP) model in prediction of diabetes mellitus (DM) complicated with coronary heart disease (CHD) by TCM personality and constitutions; To provide a new method for objective prediction. Methods This research utilized single factor logistic regression to filter out variables, which were significant factors of TCM personality and constitutions as analytic variables for MLP and multivariate logistic regression to establish TCM prediction model of personality and constitutions for DM complicated with CHD. The prediction efficiency of the above models were tested by receiver operating characteristic curve (ROC curve). Results The sensitivity, specificity and AUC of MLP were 0.915 (0.862, 0.968), 0.846 (0.793, 0.912) and 0.913 (0.806, 0.987) respectively, which was better than the logistic regression, while these indexes of logistic regression were 0.834 (0.695, 0.953), 0.762 (0.623, 0.901), and 0.869 (0.730, 0.941) respectively. Conclusion The MLP model is better than logistic regression model in prediction of DM complicated with CHD by TCM personality and constitutions.
