Abstract

Emotions
play a significant and powerful role in everyday life of human beings.
Developing algorithms for computers to recognize emotional expression is widely
studied area. In this study, emotion recognition from  Galvanic Skin Response signals was performed
using time domain, wavelet and empirical mode decomposition based features.
Valence and arousal have been categorized and relationship between physiological
signals and arousal and valence has been studied using k-Nearest Neighbors,
Decision Tree, Random Forest and Support Vector Machine algorithms. We have
achieved 81.81% and 89.29% accuracy rate for arousal and valence respectively.
