Special Issue Information

Dear Colleagues,

The capability to learn from data is a proper feature of machine learning (ML). MLs are based on the idea that systems can learn from data whether suitably trained. However, such systems do not provide the expected results because the degree of knowledge is poor or even missing. For designing suitable artificial intelligent systems, either learning and knowledge are needed. Thus, the task of fuzzy logic is to add knowledge to the systems for improving their performances. The combination between knowledge and learning has given rise to the design of hybrid intelligent systems. The optimization of this kind of systems is also based on nature-inspired optimization algorithms. Therefore, ML nature-inspired systems can be enhanced by adding fuzzy techniques. This Special Issue provides a platform for researchers from academia and industry to present their novel and unpublished works in the domain of intelligent control, robotics, intelligent transportation systems, pattern recognition, medical diagnosis, decision systems, and optimization of complex problems.

Emotion recognition using facial images has been a challenging task in computer vision. Recent advancements in deep learning has helped in achieving better results. Studies have pointed out that multiple facial expressions may present in facial images of a particular type of emotion. Thus, facial images of a category of emotion may have similarity to other categories of facial images, leading towards overlapping of classes in feature space. The problem of class overlapping has been studied primarily in the context of imbalanced classes. Few studies have considered imbalanced facial emotion recognition. However, to the authors’ best knowledge, no study has been found on the effects of overlapped classes on emotion recognition. Motivated by this, in the current study, an affinity-based overlap reduction technique (AFORET) has been proposed to deal with the overlapped class problem in facial emotion recognition. Firstly, a residual variational autoencoder (RVA) model has been used to transform the facial images to a latent vector form. Next, the proposed AFORET method has been applied on these overlapped latent vectors to reduce the overlapping between classes. The proposed method has been validated by training and testing various well known classifiers and comparing their performance in terms of a well known set of performance indicators. In addition, the proposed AFORET method is compared with already existing overlap reduction techniques, such as the OSM, ν-SVM, and NBU methods. Experimental results have shown that the proposed AFORET algorithm, when used with the RVA model, boosts classifier performance to a greater extent in predicting human emotion using facial images.
