  1. The confusion matrix shows the probability of declaring a class w j if the feature set from class w i was at the input of the classifier. The three classes examined are listed in the left column and the declared classes are listed in the top row. The values within the main diagonal illustrate the probability of the correct classification when the input class w i is correctly declared as w i .
