摘要

先进的面部表情识别技术可以显著增强人机交互，为人类提供智能服务。介绍了一种基于增强卷积神经网络的面部表情识别方法。通过将SENET注意机制集成到ConvNeXt块中，有效增强了关键特征信息的提取。此外，引入焦点损失（focal loss， FL）函数优化了网络模型的分类性能。实验结果表明，与其他深度学习模型相比，改进的ConvNeXt网络具有更高的准确率，在RAF-DB和FER2013数据集上的准确率分别为83.8%和70.4%。

Research on Facial Expression Recognition Method Based on Improved ConvNeXt

Advanced facial expression recognition technology can significantly enhance human-computer interaction and improve intelligent services for humans. This paper introduces a novel facial expression recognition method utilizing an enhanced ConvNeXt network. By integrating the SENET attention mechanism into the ConvNeXt block, key feature information extraction is effectively enhanced. Additionally, the incorporation of the focal loss (FL) function optimizes the classification performance of the network model. Experimental results show that the improved ConvNeXt network achieves higher accuracy compared to other deep learning models, with accuracy rates of 83.8% and 70.4% on the RAF-DB and FER2013 datasets, respectively.
