Using three to five key items from MMSE and CASI as predictors, we developed six machine learning models, including Lasso, classification and regression tree (CART), random forest (RF), extreme gradient boosting, support vector machine (SVM), and artificial neural networks to identify those with a CASI score below the 20th percentile of age\u2010 and education\u2010matched norms in the derivation set. We then evaluated the predictive performance of these models in the validation set.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The derivation samples (<jats:italic>n<\/jats:italic>\u2009=\u2009357) had a mean (SD) age of 64.13 (11.92) years and a mean education level of 8.76 (4.91) years. Around 40% of participants had a CASI score below the 20th percentile. Among all models, the RF model achieved the highest performance of prediction, with an accuracy of 0.94, an area under the curve (AUC) of 0.95, and an F1 score of 0.92 in the validation set. The other models, except for CART, performed equally well in terms of AUC.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our study demonstrates that using
