5-fold and 10-fold cross-validation for four-class classification using different classifiers

Method	Classifier	Mean accuracy	SD
5-fold cross validation for four-class classification	Simple tree	63.96	0.0243
	Linear SVM	73.09	0.0115
	Weighted KNN	68.07	0.0172
10-fold cross validation for four-class classification	Simple tree	63.93	0.0210
	Linear SVM	73.44	0.0072
	Weighted KNN	68.32	0.0116

SD – Standard deviation; SVM – Support vector machine; KNN – K-nearest neighbor
