A novel three-stage decision method improves subject-independent emotion recognition from physiological signals by addressing individual differences.
May enhance multi-subject physiological monitoring; leaves open prospective validation before clinical or research adoption.
The proposed three-stage decision method solves a crucial issue which is 'individual differences' in multi-subject emotion recognition and overcomes the suboptimal performance with respect to direct classification of multiple emotions. Our study supports the observation that the proposed method represents a promising methodology for recognizing multiple emotions in the multi-subject context.
