Towards a robust BCI: error potentials and online learning

2006, 研究的问题是如何提高BCI的鲁棒性?。题目也说得比较清楚了,我们主要关注 ErrP 这一部分。

abstract

背景: BCIs很有潜力,但是仍有很多问题有待解决。

IDIAP认为有一些领域很有机会提升BCI的 robustness, flexibility, reliability.

工作:

  • recognition of cognitive error states, that is, identifying errors through the brain’s reaction to mistakes.
  • online adaption of the classifier.

Intro

ErrP 大致分两种:

  • response:make and know immediately
  • feedback: make until informed by feedback

Result

出现了一种新的 “Interaction ErrP”

Methods

采用简单的按键驱动,但是BCI会故意出错,从而引起ErrP的出现。
