基于集成学习与聚类联合标注的多模态个体情绪识别OACSTPCD
Multimodal individual emotion recognition with joint labeling based on integrated learning and clustering
针对通用情绪识别模型面对不同个体时的低识别精度问题,提出一种基于集成学习与聚类联合标注的多模态个体情绪识别方法.该方法首先基于公共数据集训练通用情绪识别模型,然后分析公共数据集数据与个体无标签数据的分布差异,建立跨域模型来预测和标注个体数据的伪标签.同时,对个体数据进行加权聚类并标注聚类标签,利用聚类标签与伪标签进行联合标注,筛选高置信度样本进一步训练通用模型,得到个性化情绪识别模型.实验采集3名被试的3种情绪数据并使用该方法标注,最后优化得到的个性化模型对3种情绪的平均识别精度达到80%以上,相比原通用模型,至少提升了35%.
To address the low recognition accuracy of generic emotion recognition models when faced with different indi-viduals,a multimodal individual emotion recognition technique based on joint labelling with integrated learning and clus-tering was proposed.The method first trained a generic emotion recognition model based on a public dataset,then anal-lysed the distributional differences between the data in the public dataset and the unlabelled data of individuals,and estab-lished a cross-domain model for predicting and labelling pseudo-labels of individual data.At the same time,the individual data were weighted clustered and labelled with cluster labels,and the cluster labels were used to jointly label with pseudo-labels,and high confidence samples were screened to further train the generic model to obtain a personalized emotion rec-ognition model.Using this method to annotate these data with the experimentally collected data of 3 emotions from 3 sub-jects,the final optimized personalized model achieved an average recognition accuracy of more than 80%for the 3 emo-tions,which was at least a 35%improvement compared to the original generic model.
