Spatial filters for the classification of event-related potentials
Touradj Ebrahimi, Ulrich Hoffmann
Spatial filtering is a widely used dimension reduction method in electroencephalogram based brain-computer interface systems. In this paper a new algorithm is proposed, which learns spatial filters from a training dataset. In contrast to existing approache ...
2006A Boosting Approach to P300 Detection with Application to Brain-Computer Interfaces
Touradj Ebrahimi, Ulrich Hoffmann
Gradient boosting is a machine learning method, that builds one strong classifier from many weak classifiers. In this work, an algorithm based on gradient boosting is presented, that detects event-related potentials in single electroencephalogram (EEG) tri ...
SPIE2005Application of the Evidence Framework to Brain-Computer Interfaces
Touradj Ebrahimi, Ulrich Hoffmann
A brain-computer interface (BCI) is a communication system, that implements the principle of "think and make it happen without any physical effort". This means a BCI allows a user to act on his environment only by using his thoughts, without using peripher ...
