The ROC curves of different machine learning models for predicting different obesity class. The blue curve represents the non-obesity (class 0), the yellow curve represents the class 1 obese (class 1), and the red curve represents the class 2 obesity (class 2). The micro-average curve is a weighted average of true positive and false positive rates for all samples, represented by a red dashed line. The macro-average curve is the average of the ROC curves for the three class, represented by a blue dashed line.
