Filter Bank CSP

Post by smr.shahshahani »

Dear all,
Is there any planning on adding the Filter Bank CSP algorithm to Openvibe?
It's really a necessary block to be added to the package.
Thanks

Hello,

So far, we don't have feature selection yet in OpenViBE, but that is planned! When that would be available, you'll have everything needed to do FBCSP.
In the mean time, you can still use a filter bank and learn CSP filters for each band. If you don't extract too many filters, that still gives very good results.

I hope this helps,

Best,
Fabien

Thanks for your response.
How can I define a filter bank in Openvibe?

There is no box to define a filter bank directly, but you can simply use multiple "temporal filter" boxes, each one designing one of the filter in the bank.
