📝 摘要(中文)
嗅觉感官评估在食品、服装和化妆品等领域具有广泛应用。传统的人工嗅觉评估重复性差,而电子鼻等机器嗅觉难以反映人类的真实感受。嗅觉脑电图(EEG)包含与嗅觉偏好相关的气味和个体特征,具有独特优势。然而,跨主体的嗅觉EEG识别难度较大,限制了其应用。本文提出了一种结合电子鼻和嗅觉EEG的多模态学习方法,建立了数据采集和预处理范式,并提出了互补的多模态数据挖掘策略,成功实现了24名受试者的跨主体嗅觉偏好识别,识别效果优于现有方法,显示出在实际嗅觉评估中的潜力。
🔬 方法详解
问题定义:本文旨在解决跨主体嗅觉偏好识别中的困难,现有方法在个体差异和数据重复性方面存在显著不足。
核心思路:通过结合电子鼻和嗅觉EEG,利用多模态数据的互补性,提取气味信息和个体情感特征,以提高识别准确性。
技术框架:整体方法包括数据采集、预处理、特征提取和融合四个主要模块。首先收集电子鼻和EEG数据,然后进行预处理,接着提取共同和个体特征,最后进行特征融合以实现识别。
关键创新:提出的互补多模态数据挖掘策略是本研究的核心创新,能够有效挖掘并融合不同模态的数据特征,显著提升识别性能。
关键设计:在特征提取阶段,采用了针对EEG信号的特定滤波器和特征选择算法,确保提取的特征能够准确反映个体的情感状态,同时在融合阶段使用了加权融合策略以优化最终识别结果。

📄 摘要(原文)
Odor sensory evaluation has a broad application in food, clothing, cosmetics, and other fields. Traditional artificial sensory evaluation has poor repeatability, and the machine olfaction represented by the electronic nose (E-nose) is difficult to reflect human feelings. Olfactory electroencephalogram (EEG) contains odor and individual features associated with human olfactory preference, which has unique advantages in odor sensory evaluation. However, the difficulty of cross-subject olfactory EEG recognition greatly limits its application. It is worth noting that E-nose and olfactory EEG are more advantageous in representing odor information and individual emotions, respectively. In this paper, an E-nose and olfactory EEG multimodal learning method is proposed for cross-subject olfactory preference recognition. Firstly, the olfactory EEG and E-nose multimodal data acquisition and preprocessing paradigms are established. Secondly, a complementary multimodal data mining strategy is proposed to effectively mine the common features of multimodal data representing odor information and the individual features in olfactory EEG representing individual emotional information. Finally, the cross-subject olfactory preference recognition is achieved in 24 subjects by fusing the extracted common and individual features, and the recognition effect is superior to the state-of-the-art recognition methods. Furthermore, the advantages of the proposed method in cross-subject olfactory preference recognition indicate its potential for practical odor evaluation applications.
