摘要:

随着机器学习的快速发展,基于脑电图(EEG)和眼动信号的大脑活动识别与分析已达到很高的成熟度。使用深度学习模型学习EEG和眼动特征被证明可有效对大脑活动进行分类。专注状态指对任务或想法的高度集中,可通过反映大脑活动变化的眼动行为区分专注与非专注状态。通过计算眼动信号中的双眼聚焦点视差并整合相关EEG特征,我们提出了一种专注状态标注方法。经生物采集设备处理原始数据得到的综合数据集,既包含EEG特征,也包含通过眼动标注的专注标签。在多个深度学习模型(尤其是Transformer)上进行的大量训练与测试,在受试者依赖实验中取得了90.16%的准确率。跨受试者实验、关键频段与脑区分析证实了该方法的有效性,验证了其泛化性并提供了生理学解释。

英文摘要:

With the rapid advancement in machine learning, the recognition and analysis of brain activity based on EEG and eye movement signals have attained a high level of sophistication. Utilizing deep learning models for learning EEG and eye movement features proves effective in classifying brain activities. A focused state indicates intense concentration on a task or thought. Distinguishing focused and unfocused states can be achieved through eye movement behaviors, reflecting variations in brain activities. By calculating binocular focusing point disparity in eye movement signals and integrating relevant EEG features, we propose an annotation method for focused states. The resulting comprehensive dataset, derived from raw data processed through a bio-acquisition device, includes both EEG features and focused labels annotated by eye movements. Extensive training and testing on several deep learning models, particularly the Transformer, yielded a 90.16% accuracy on the subject-dependent experiments. The validity of this approach was demonstrated, with cross-subject experiments, key frequency band and brain region analyses confirming its generalizability and providing physiological explanations.
