Confusion matrix obtained from the classification of the three behaviours, using SVM with a six dimensional feature vector and RBF kernel function. The bold numbers indicate correct classification. The samples are 100 ms audio sequences. The notation A/B refers to the notation Test A and Test B, described in the Section 2.7. A: Classification where data has been divided based on date; B: Classification where data has been mixed.
