CSP Spatial Filter Trainer - Algorithm implementation

Post by Ramiro »

Hi,
Can I have access to the code of the algorithm implemented in the box "CSP Trainer Spatial Filter"?
Because I want to know exactly how it works and make modifications if necessary.

Surfing on the internet I found this file:
https://github.com/antoche/openvibe/blo ... rainer.cpp

Is this the code that is currently implemented? I have installed version 1.0.1 of OpenViBE.

Thank you.

Regards

Hi Ramiro, the link you mention is some third-party fork of an old version of OpenViBE.

The official openvibe source code for the current and previous versions can be obtained via the following page,

http://openvibe.inria.fr/downloads/

In the next release (due very soon) we will have a regularized version of CSP which might be of interest to you. At the moment its only in the 'integration-1.1' git branch,

Happy hacking,
Jussi

Hi, thanks for reply.

One more question: Is this version working properly? That is, Could I download the 'integration-1.1' git branch, build the software and use the regularized version of CSP smoothly?

Probably not worth the trouble, the actual release should be due today. The new CSP included.

Hello, do you have the algorithm implemented in Matlab?

Because I have tried the BioSig version: "csp.m" (without regularized) and I have gotten different spatial filters from the version of OpenViBE: "CSP Trainer Spatial Filter" (without regularized).

In case you do not have this algorithm implemented, do you know an algorithm already implemented in Matlab which is more similar to the "CSP Trainer Spatial Filter" version than the BioSig one?

Thanks in advance

Regards
