摘要:

脑机接口(BCI)系统通常是专门为每个主题的基础上运动想象。因此,这些网络的可用性已成为一个重大挑战。网络必须为每个用户单独设计,这对用户来说是耗时的。因此,本研究提出了一种方法,通过该方法的校准时间显着减少,而分类精度增加。在这种方法中,我们校准的特征提取的运动想象任务划分的特征提取的休息状态到睁开眼睛和闭上眼睛的模式和受试者移动他的眼睛的状态。使用睁开眼的静息状态信号的SVM分类器获得了最好的分类精度,提高了3.64%到74.04%。在本文中,我们还研究了休息状态信号的记录时间和眼睛状态对分类精度的影响。

英文摘要:

Brain-computer interface (BCI) systems are usually designed specifically for each subject based on motor imagery. Therefore, the usability of these networks has become a significant challenge. The network has to be designed separately for each user, which is time-consuming for the user. Therefore, this study proposes a method by which the calibration time is significantly reduced while the classification accuracy is increased. In this method, we calibrated the features extracted from the motor imagery task by dividing the features extracted from the resting-state into both open-eye and closed-eye modes and the state in which the subject moves his eyes. The best classification accuracy was obtained using the SVM classifier using the resting-state signal in the open eye, which increased by 3.64% to 74.04%. In this paper, we also investigated the effect of recording time of the resting-state signal and the impact of eye state on the classification accuracy.
