Description:

Execute StudentImageCollectionActivity for one student
Let the background training train the student
Execute the Authentication with another person

Expected Result:

The authentication should fail 3 times and then redirect to the StudentImageCollectionEvent

Actual Result:

The authentication doesn't fail because there is only one student trained and the SVM probability is per class, so 1 class = 100% accuracy

Solution

Replace SVM probability classifier with SVM or KNN distances with a threshold
