OpenViBE forum

Hello,

I want to create a scenario similar to the motor-imagery-bci-3-online-incremental.xml but instead of Laplacian I want to use CSP spatial filter. Is it possible to create something like this? I am asking because first we have to train csp filter and save the configuration file in order to use it later. Is it correct if I do csp training, classifier training and processor in the same scenario?

Thanks,
Sofia

Hi Sofia,

Unfortunately no, you cannot train your CSP spatial filter at the same time as using its for the classifier training.

Also, the spatial filter box does not contain a way to reload it's configuration dynamically, so you cannot do some sort of incremental CSP either, the same way incremental classification is done.

As you may have seen, the exemple provided with OpenViBE motor-imragery-CSP indeed requires an extra training scenario for the CSP training.
However, you could also use the incremental classification scenario as the online scenario afterwards.

Cheers,
Thomas

Thank you for your response Thomas!
