AI Technical Summary

Technical Problem

Existing multimodal sentiment analysis technologies struggle to effectively combine audio and image modal information to dynamically adjust the weight of text information. Furthermore, existing fusion strategies are ill-equipped to handle intermodal conflicts and redundant information, impacting the accuracy of sentiment recognition.

Method used

We employ a cross-modal dynamic convolution-based approach to acquire primary features, word-level alignment features, and high-level features from the video. We then utilize a bidirectional GRU network and cross-modal dynamic convolution for multimodal interaction, and combine this with a multi-head attention mechanism for feature fusion to output emotion recognition results.

Benefits of technology

It improves the accuracy of sentiment classification, effectively models the local information of the temporal dimension of modality, avoids important information being buried, and enhances the effect of sentiment recognition.

Abstract

本发明涉及自然语言处理、深度学习、多模态情感分析领域,涉及一种基于跨模态动态卷积的视频多模态情感识别方法、装置及计算机设备,所述方法包括使用ERNIE2.0预训练模型、DCCN、ResNet‑152和胶囊网络分别对文本、音频、图像提取出单模态低级特征;使用词对齐对三个模态特征进行对齐;采用双向GRU对上述特征进行处理,得到各模态高级特征;利用跨模态动态卷积对三个模态特征进行交互;拼接各个模态的跨模态交互特征和高级特征,并利用多头注意力机制融合;最后输入到softmax函数中得到情感识别结果;本发明很好的融合了各单模态特征,有效挖掘视频中所表达的情感信息,从而提升了多模态情感识别的准确率及效率。
