Supervised Linear Classification Performance Based on Marginal Probability for Two Groups

F. Z. Okwonu · Journal of Advances in Mathematics and Computer Science · 2014

The conventional technique to determine classification performance for the linear classification techniques strictly depends on the mean probabilities of correct classification or misclassification. Based on the mean probabilities of correct classification, robustness can be dete...
