Special Issue Information

Dear Colleagues,

Emotions are physical and mental states brought on by neurophysiological changes, encompassing a range of feelings, thoughts and behaviors. Human emotions provide crucial information in both psychology and physiology. Emotion recognition, the process of identifying emotion, can significantly benefit areas such as healthcare, human–computer interaction, and customer service. For instance, emotion information can support the diagnosis and monitoring of mental health conditions and provide feedback to therapists. Understanding the emotions of users better can enhance user experience by making human–computer interfaces more responsive and adaptive to emotional states. Additionally, analyzing consumer emotions can help researchers to tailor marketing strategies and improve customer satisfaction. Empowered by the novel algorithms in machine learning, particularly in deep learning, along with the availability of datasets, people have made impressive progress in emotion recognition studies.

However, challenges remain in the field of emotion recognition. Theoretically, various aspects of emotion recognition paradigms, such as dimensions and metrics, warrant further study. There are also model-related challenges, including issues due to generalization, subject-dependencies, and modality-dependencies. Other than that, there are plenty of potential applications of emotion recognition, such as some specific healthcare applications, that remain underexplored. Additionally, current publicly available datasets for emotion recognition fall short of supporting comprehensive research needs.

We are delighted to announce this Special Issue dedicated to the burgeoning field of emotion recognition, inviting researchers and practitioners to submit their cutting-edge work on advanced technologies and innovative applications. This Special Issue will provide a comprehensive platform for the latest developments, fostering collaboration and sharing insights that drive the future of emotion recognition.

Recommended topics include, but are not limited to, the following:

  • Applications of emotion recognition (e.g., healthcare, human–computer interaction);
  • Novel AI models and approaches for emotion recognition;
  • Theory and paradigm of emotion recognition (e.g., dimension and metrics);
  • Multimodal emotion recognition;
  • Sensors and hardware for emotion recognition;
  • Datasets for emotion recognition.

Anxiety is a significant mental health concern that can be effectively monitored using physiological signals such as galvanic skin response (GSR). While the potential of machine learning (ML) algorithms to enhance the classification of anxiety based on GSR signals is promising, their effectiveness in this context remains largely underexplored. This study addresses this gap by investigating the performance of three commonly used ML algorithms, support vector machine (SVM), K-nearest neighbor (KNN), and random forest (RF), in classifying anxiety and stress activity using a benchmark dataset. We employed two feature extraction methods: traditional statistical feature extraction and an innovative automatic feature extraction approach utilizing a 14-layer autoencoder, aimed at improving classification performance. Our findings demonstrate the effectiveness of using GSR signals and the robust performance of the KNN algorithm in accurately classifying anxiety levels. The KNN algorithm achieved the highest accuracy in both the statistical and automatic feature extraction approaches, with results of 96.9% and 98.2%, respectively. These findings highlight the effectiveness of KNN for anxiety detection and emphasize the need for advanced feature extraction techniques to enhance classification outcomes in mental health monitoring.
