RETRACTED: Multimodal Emotion Recognition Model Based on a Deep Neural Network with Multiobjective Optimization (Retracted Article)

With the rapid development of deep learning and wireless communication technology, emotion recognition has received more and more attention from researchers. Computers can only be truly intelligent when they have human emotions, and emotion recognition is its primary consideration. This paper proposes a multimodal emotion recognition model based on a multiobjective optimization algorithm. The model combines voice information and facial information and can optimize the accuracy and uniformity of recognition at the same time. The speech modal is based on an improved deep convolutional neural network (DCNN); the video image modal is based on an improved deep separation convolution network (DSCNN). After single mode recognition, a multiobjective optimization algorithm is used to fuse the two modalities at the decision level. The experimental results show that the proposed model has a large improvement in each evaluation index, and the accuracy of emotion recognition is 2.88% higher than that of the ISMS_ALA model. The results show that the multiobjective optimization algorithm can effectively improve the performance of the multimodal emotion recognition model.
