Since you get the NB classifiers' parameters from Task $2,$ you need to implement their calculation formula according to their Mathematical Expressions. Then you use your implemented classifiers to classify$/$predict all the unknown labels of newly coming data points $($your test data points converted from your original testset for both digit$0$ and digit$1).$ Thus, in this task, you need to work with the testset for digit$0$ and digit$1(2$ Numpy Arrays: test$0$ and test$1$ mentioned above$)$ and you need to predict all the labels of them.
