[h, H_Pxy, H_Px, H_Py, MI_Pxy... File Information Description Entropy_triangle is a function that implements two tools to analyze the behavior of multiple-class, or multi- class, classifiers by means of entropic measures on their confusion matrix or contingency table. First we obtain a balance equation on the entropies that captures interesting properties of the classifier. Second, by normalizing this balance equation we first obtain a 2-simplex in a three-dimensional entropy space and then the de Finetti entropy diagram or entropy triangle.
