これは私が持っているものです:
training_data = Testdata;
target_class = TestDataLabels;
%# train model
nb = NaiveBayes.fit(training_data, target_class, 'Distribution', 'mn');
%# prediction
class1 = nb.predict(UnseenTestdata);
%# performance
cmat1 = confusionmat(UnseenTestDataLabels, class1);
acc1 = 100*sum(diag(cmat1))./sum(cmat1(:));
fprintf('Classifier1:\naccuracy = %.2f%%\n', acc1);
fprintf('Confusion Matrix:\n'), disp(cmat1)
誰かが疑問に思っている場合、データセットは 4940201x42 です。
