摘要

情感识别是人机交互智能化的关键环节.脑电（ElectroEncephaloGram，EEG）信号因其蕴含丰富的生物信息且难以伪装，成为情感分析的重要载体.然而，EEG信号特征复杂多变，且存在显著的个体间差异和时变性，导致传统机器学习方法的情感分类准确率低、泛化能力差.针对这一挑战，本文提出了一种基于重

构迁移子空间多视角领域适应（Reconstructed Transfer Subspace based Multi-View Domain Adaptation，RTS-MVDA）方法.该方法将不同特征视为独立视角，通过多视角学习探索各视角的独特性和重要性，并探索其互补关系.其核心在于将源域与目标域的多视角数据投影到一个带有低秩约束的重构迁移子空间.在该子空间中，RTS-MVDA一方面利用重构项恢复原始数据信息，并通过低秩表示保留主要判别信息；另一方面，RTS-MVDA实施线性变换对齐源域和目标域，减少领域间的分布差异.此外，RTS-MVDA构建多视角监督判别项和全局结构保持项，多视角监督判别项利用源域标签信息增强类内紧凑性和类间分离性，全局结构保持项保持数据在迁移子空间中的全局结构分布，从而更有效地将源域的判别知识迁移至目标域.在公开DEAP（Database for Emotion Analysis using Physiological signals）数据集上的实验验证表明：所提RTS-MVDA方法在唤醒度和效价维度上分别达到了73.15%和72.91%的平均准确率，其Precision、Recall和

-score指标均显著优于相关对比方法，有效提升了跨被试EEG情感识别的准确性和泛化能力.

Abstract

Emotion recognition is the key link of intelligent human-computer interaction. Electroencephalogram (EEG) has become an important carrier of emotion analysis because it contains rich biological information and is difficult to disguise. However

EEG signal features are complex and changeable

and there are significant individual differences and time variability

which lead to low accuracy and poor generalization ability of traditional machine learning methods. To address these challenges

this paper proposes a reconstructed transfer subspace based multi view domain adaptation (RTS-MVDA). This method regards different features as independent perspectives

explores the uniqueness and importance of each perspective through multi perspective learning

and mining their complementary relationship. Its core is to project the multi view data of the source domain and the target domain into a reconstruction migration subspace with low-rank constraints. In this subspace

RTS-MVDA

on the one hand

uses the reconstructed items to restore the original data information

and retains the main discrimination information through the low-rank representation; on the other hand

RTS-MVDA implements linear transformation to align the source domain and target domain

reducing the distribution difference between domains. In addition

RTS-MVDA constructs multi view supervised discriminant

and global structure preserving item. The former uses source domain label information to enhance intra class compactness and inter class separation

while the latter maintains the global structure distribution of data in the migration subspace

so as to more effectively migrate the discriminant knowledge of the source domain to the target domain. The experimental verification on the public database for emotion analysis using physiological signals (DEAP) dataset shows that the average accuracy of the proposed RTS-MVDA method in arousal and valence is 73.15% and 72.91%

respectively. Its precision

recall and

-score are significantly better than the related comparison methods

effectively improving the accuracy and generalization ability of cross-subject EEG emotion recognition.
