EEG-Analysis for Classification of Touch-Induced Affection by Type-2 Fuzzy Sets

The paper aims at classifying the brain response to touch-induced affection aroused in human subjects into four classes: love, fondness, devotion and respect using a novel vertical slice based General Type-2 Fuzzy classifier. The novelty of research here lies in the design of vertical slice based General Type-2 Fuzzy Classifier, capable of classifying finer changes in the brain activation patterns due to changes in the touch nourishment on a subject by different people, including spouse, children, graces of the Almighty and parents. Experiments undertaken confirm that for most of the subjects the above four classes are prominent in the brain activation patterns. The frontal lobe is more activated in devotion and respect, whereas temporal lobe is more activated in fondness and love. The General Type-2 fuzzy classifier designed for classification of four affection classes yield high classification accuracy over 98 % in comparison to existing type-l fuzzy and other classifies. The proposed scheme of touch-induced affection classification can be interestingly applied to measure subjective sensitivity of healthy and psychologically disabled people.
