背景情况:

电脑电图 (EEG) 信号的非静止性对大脑计算机接口 (BCI) 性能提出了重大挑战.
脑电图数据的特定会话变化往往需要频繁的重新校准,这阻碍了BCI的实际实施.

研究的目的:

为跨会话BCI任务开发一种新的方法,以减轻EEG信号的非静止变化.
为了减少特定会话的信息,同时保留与任务相关的信号,以提高BCI准确性.

主要方法:

一个受监督的自动编码器被用来压缩和重建高维EEG输入.
自动编码器的目标功能包括无监督的重建错误最小化和监督的术语,以删除会话身份并优化分类.
该方法在三个运动图像数据集中进行了评估.

主要成果:

提出的方法有效地解决了跨会期BCI任务中的域调整挑战.
在运动图像数据集上,性能超过了原始交叉会话和会话内方法.
该方法成功地减少了特定于会话的信息,消除了非静止信号.

结论:

这种新的方法消除了对新会话数据的需求,使其无需监督新会话,并减少了重新校准的需求.
有效地消除非静态EEG信号的噪声,提高了BCI模型的准确性.
未来的应用可能会扩展到其他BCI任务和分析用于认知过程调查的残留信号.
