A Comprehensive Review for Emotion Detection Based on EEG Signals: Challenges, Applications, and Open Issues

Abstract: Emotion classification based on physiological signals has become a hot topic in the past decade. Many studies have attempted to classify emotions using various techniques, to discover human emotions accurately. This study focused on listing the most recent studies that have classified emotions based on electroencephalogram (EEG) signals. This study also focused on solving the problems and challenges facing researchers in emotion classification and EEG applications used in several fields. The plan of this study… Show more

“…[6]. The studies utilized machine learning algorithms such as Gaussian Mixture Model (GMM), clustering algorithms like K means, Machine learning classifiers like the support vector machine, and artificial neural networks like ELM's (Extreme learning machine) [7] to classify emotional EEG data into different categories. The research also involved pre-processing techniques such as bandpass filtering, Welch period technique, Digital Signal Processing (DSP), Power Spectral Density, Wavelet Decomposition and transforms, and Hjorth Parameter for extracting feature vectors from filtered EEG data [8].…”

“…(7) Artificial Neural Networks (ANNs) are trained on the EEG signal to recognize different emotional states based on the extracted features [17]. (8) Deep learning techniques exhibit promising results in EEG-based emotion recognition, with ongoing exploration to develop models capable of capturing the intricate and dynamic patterns of brain activity associated with distinct emotional states [18][19][20][21]. (9) Transfer learning allows models trained on one dataset to adapt to another dataset with minimal retraining.…”
