Question: What is the performance of classifiers?
Answer: Table TABREF10,  The KNN classifier seem to perform the best across all four metrics. This is probably due to the multi-class nature of the data set,  While these classifiers did not perform particularly well, they provide a good starting point for future work on this subject
Alternative answer: Using F1 Micro measure, the KNN classifier perform 0.6762, the RF 0.6687, SVM 0.6712 and MLP 0.6778.
