摘要:

大脑神经网络表征了不同情绪状态的各种信息传播模式。然而,基于传统图论的统计特征可能忽略了网络的空间差异。为了揭示这些内在的空间特征,提高情感识别的稳定性,我们提出了一个层次化的框架,可以执行多情感相关的空间网络拓扑模式(MESNP)的多情感识别相结合的监督学习和集成协同决策策略。为了评估我们提出的MESNP方法的性能,我们使用两个公共数据集进行离线和模拟在线实验,即,Mahnob和Deap。实验结果表明,MESNP可以显著提高对多种情绪的分类性能。MAHNOB-HCI和DEAP离线实验的最高准确率分别达到99.93%(3类)和83.66%(4类)。对于模拟在线实验,我们也获得了最好的分类准确率为100%(3类)的MAHNOB和99.22%(4类)的DEAP建议MESNP。这些结果进一步证明了MESNP在多分类情感任务中结构化特征提取的有效性。

英文摘要:

Brain neural networks characterize various information propagation patterns for different emotional states. However, the statistical features based on traditional graph theory may ignore the spacial network difference. To reveal these inherent spatial features and increase the stability of emotional recognition, we proposed a hierarchical framework that can perform the multiple emotion recognitions with the multiple emotion-related spatial network topology patterns (MESNP) by combining a supervised learning with ensemble co-decision strategy. To evaluate the performance of our proposed MESNP approach, we conduct both off-line and simulated on-line experiments with two public datasets i.e., MAHNOB and DEAP. The experiment results demonstrated that MESNP can significantly enhance the classification performance for the multiple emotions. The highest accuracies of off-line experiments for MAHNOB-HCI and DEAP achieved 99.93% (3 classes) and 83.66% (4 classes), respectively. For simulated on-line experiments, we also obtained the best classification accuracies with 100% (3 classes) for MAHNOB and 99.22% (4 classes) for DEAP by proposed MESNP. These results further proved the efficiency of MESNP for structured feature extraction in mult-classification emotional task.
