Bug Description
When I conducted a decision-tree and neural network to classify data, I realized that the labels identifying clusters in the decision boundary matrix should have been in the reverse order. I mean in my case according to the decision boundary matrix, as students get grades in courses, they classified as fail. I attached data and the output.
Expected Behaviour
The labels regarding the cluster in the decision boundary matrix should have been in the reverse coded.
Steps to Reproduce
I repeated with different data set. The results is the same. There is a problem with the point labels in decision boundary matrix. For instance, if 0 is fail and 1 is success like in my case, in the matrix fail is pink and success is the green points. When the matrix is examined, pink labels (fail) cluster students who get good grades not ust one course for all courses, which do not have a sense. My guess, the pink ones should have been success and green ones should have been fail.
