Abstract TP391; 针对事件相关电位(event-related potential,ERP)在跨被试场景下检测精度不高的问题,提出了一 种基于图表征和双重注意力机制的卷积循环神经网络模型.该模型采用不依赖于被试和任务的图来表征脑电信号中的空间信息,并级联卷积神经网络(convolutional neural network,CNN)和长短期记忆网络(long short-term memory net-work,LSTM)形成CNN-LSTM基础框架,同时嵌入双重注意力机制(即选择性内核卷积和自注意力机制)以充分提取不同被试脑电信号的时空特征,从而提高跨被试场景下的ERP检测精度.在基于快速序列视觉呈现范式的大规模基准数据集上的实验结果表明,与现有的7种ERP检测方法相比,所提方法在跨被试场景下具有显著的优越性.
