Classification of EEG signals represented by AR models for cognitive tasks - a neural network based method

Plausibility assessment of a 2-state self-paced mental task-based BCI using the no-control performance analysis

Most of them classify mental tasks to some extent, but only a few of them report the resultant false positive rate or the confusion matrix (Palaniappan, 2005a;…”

“…Most of them classify mental tasks to some extent, but only a few of them report the resultant false positive rate or the confusion matrix (Palaniappan, 2005a;Nakayama and Inagaki, 2006;Anderson et al, 2006;. Some report the classification error (Maiorescu et al, 2003;Rao and Derakhshani, 2005;Nakayama et al, 2007). The remaining studies report the correct classification rates for the different mental tasks.…”

An EEG (Bio) Technological System For Assisting The Disabled People

“…the C3, C4, P3, P4, 01 and 02 positions on the scalp. During For this test we used the same BEG database that was also these recordings the 4 involved subjects performed (without used by us in two other previous studies [10], [11], and that verbalization, with eyes closed) the following mental tasks:…”

“…matrix (representing the data flow between the features In order to classify the tasks -having as final goal the aim extractions and the classification dynamic link library) -were to test the EEG bio-instrumental system and not to obtain the only steps required to dynamically implement the new better performances -, we used the same approach presented structure. As a result, we obtained a different system having in [10]. For each channel 6 AR coefficients were extracted; different characteristics.…”

Optimisation of a BCI system using the GA tehnique

“…The most frequently used features in the BCI systems are: AR coefficients [3], [4], [5], [6], AR models with exogenous inputs [6], power spectral parameters [8], [7], [9], [10], [11], statistic phase synchronization [8], [9], spatial filtering [12], mean value of the phase coherence [8], discharge frequency of a neuronal group [15], P300 wave [12], [13], [14] etc. This paper focuses on the same issue, namely that of finding more appropriate EEG features for cognitive tasks applications.…”
