 - KNN, in this part we develop the knn program and test it to compare the evolution of the accuracy depending on the number of neighbors k. (the corresponding result is named accuracy_knn and is imported in the file 'results').
 - Mlp, this final part concerns the neural networks program and it also contains the comparison of the accuracy depending on the number of epoches.
