• Enhanced computational Efficiency: a vector dissimilarity judgment criterion is established to pre-judge dissimilar vectors, improving computational efficiency by 47.8 %. • Synergy between auditory attention decoding and emotion Recognition: the study showcases a synergistic effect between auditory attention decoding and emotion recognition, achieving performance enhancement through multitask learning. • Optimal recognition Accuracy: the electroencephalogram emotion recognition achieves an optimal accuracy of 84.64 % for inter-individual recognition of positive and negative emotional states and 60.98 % for multi-emotional states across individuals, even with fewer channels in the anterior brain hemisphere. The current artificial intelligence is constrained to passively executing human command control. It cannot perceive, learn, and guide itself. Furthermore, the majority of these systems are unable to comprehend the human psychological cognitive state or emotional intention actively. To enhance the universality and generalization ability of existing emotion recognition methods, a psychological emotion state decoding method combining singular spectrum analysis and entropy measure is designed based on an electroencephalography signal. This method is developed to empower the cognitive computing system with the ability to perceive emotions. The entropy measure is accelerated by the vector dissimilarity criterion. Finally, dynamic sample entropy model learning is used to realize the cognitive calculation of psychological and emotional state recognition. The results demonstrated that the computational efficiency of the proposed decoding algorithm was significantly improved. The average recognition accuracy of positive and negative emotional states reached 82.78±16.22. The best recognition accuracy of the proposed electroencephalography emotion recognition method was 84.64 %. The proposed electroencephalography emotion recognition method demonstrated an accuracy of 64.15 % in recognizing cross-individual positive, neutral, and negative emotional states. The proposed emotion recognition method shows better universality and generalization performance, and can effectively identify people's psychological and emotional states.
