Emotion Recognition based on EEG Signals in Response to Bilingual Music Tracks
Emotions are vital for communication in daily life and their recognition is important in the field of artificial
intelligence. Music help evoking human emotions and brain signals can effectively describe human emotions. This study
utilized Electroencephalography (EEG) signals to recognize four different emotions namely happy, sad, anger, and relax in
response to bilingual (English and Urdu) music. Five genres of English music (rap, rock, hip-hop, metal, and electronic) and
five genres of Urdu music (ghazal, qawwali, famous, melodious, and patriotic) are used as an external stimulus. Twenty-seven
participants consensually took part in this experiment and listened to three songs of two minutes each and also recorded self-
assessments. Muse four-channel headband is used for EEG data recording that is commercially available. Frequency and
time-domain features are fused to construct the hybrid feature vector that is further used by classifiers to recognize emotional
response. It has been observed that hybrid features gave better results than individual domains while the most common and
easily recognizable emotion is happy. Three classifiers namely Multilayer Perceptron (MLP), Random Forest, and Hyper
Pipes have been used and the highest accuracy achieved is 83.95% with Hyper Pipes classification method.
