Spatial-Frequency Based EEG Features for Classification of Human Emotions (2024)
Journal Article

Human emotion classification without bias and unfairness is challenging because most existing image-based methods are directly or indirectly affected by subjectivity. Therefore, we propose an EEG (Electroencephalogram) based model for an accurate emo... Read More about Spatial-Frequency Based EEG Features for Classification of Human Emotions.
