Encouraging results were achieved, with the SVM model providing the best performances, outperforming the NN and MR techniques. The overall accura- cies are 64.3% (T = 0.5) and 86.8% (T = 1.0). It should be noted that the datasets contain six/seven classes (from 3 to 8/9) and these accuracies are much better than the ones expected by a random classifier. While requiring more com- putation, the SVM fitting can still be achieved within a reasonable time with current processors. For example, one run of the 5-fold cross-validation testing takes around 26 minutes.
