To analyze these results in details, we applied confusion matrix into the results of two data sets. From Table 7, it is confusion matrix for binary classification in Thai Drama Corpus. The highest accuracy of emotional class was happiness. On other hand, the sadness and fear classes had worse accuracies at 0.12 and 0.11, respectively. However, when focusing on the error of classification in anger, the most missed match was happiness. Moreover, the most error of predicted class for happiness was sadness. The emotional state between anger and happiness are quite different in state of pleasure. The happiness and sadness states are also totally stood in opposite point of pleasure. The question of these errors comes up with what features of these two opposite emotional states have shared together.
