“…In addition, CNN usually uses Softmax for classification, but experiments have shown that Softmax is not suitable in the field of FER due to the low distinction between expressions [25,26]. Currently, many researchers combine the features extracted by CNN with traditional classifiers to have better performance and achieve good results [27][28][29][30]. Liu [31] proposed a multilevel structured hybrid forest (MSHF) for joint head detection and pose estimation, which extends the hybrid framework of classification and regression forest.…”

“…It is often difficult to select the optimal parameter value, and the accuracy of fitting model is difficult to reach the expected value. Finding the right method to extract the best parameter values can improve the accuracy of the fitted model (Lin, D., 2019;Shao, Y. H., 2019). Compared with other intelligent algorithms, artificial bee colony (ABC) has the characteristics of less parameters, simple calculation and global search for optimal values (Hajimirzaei, B.,2019).…”

“…Based on ACO, Akinyelu et al [13] proposed an instance selection algorithm for SVM speed optimization. Shao et al [14] combined instance and feature selection, and proposed an uniform sparse primal and dual LSSVM model. Furthermore, Du et al [15] found that if the feature and instance selection are addressed separately, the irrelevant features may mislead the process of instance selection.…”
