Problem with classifcation algorithm

[toncho11]

Hi,

When I run the p300 bci scenario openvibe-scenarios\bci\p300-speller-xDAWN\p300-speller-3-train-classifier.xml

I get this error:

Code: Select all

IBox& l_rStaticBoxContext=this->getStaticBoxContext();

	CIdentifier a;//we need to fill this
	CString b;
	
	l_rStaticBoxContext.getSettingValue(0, b);// b is filled here I suppose
	
	a=this->getTypeManager().getEnumerationEntryValueFromName(OVTK_TypeId_ClassificationAlgorithm, b);

	if(a==OV_UndefinedIdentifier) //true
	{
		this->getLogManager() << LogLevel_Error << "Unknown classifier algorithm [" << b << "]\n"; // my code goes here!!!!!!!!!!!!!!!!!!!!!!
		return false;
	}

This method:

Code: Select all

uint64 CTypeManager::getEnumerationEntryValueFromName(
	const CIdentifier& rTypeIdentifier,
	const CString& rEntryName) const

returns a not found kind of value (0xffffffffffffffffll) for the algorithm.

I am not very much into these identificators, so I will appreciate some hints.

I am using the 13.1 code.
Also I have noticed this problem is only when the classifier is set to "LDA". When changed to "SVM" works fine.
I believe that LDA registration is missing in ovp_main.cpp project OpenViBE-plugins-classification-dynamic???

p.s. I can not checkout the code from svn from svn://scm.gforge.inria.fr/svn/openvibe/trunk

Hello,

I do not quite understand your problem. Have you created your own classification algorithm to use with the classification box? Could you be more precise about what are you trying to achieve?

As for the SVN, our servers have been upgraded and apparently there are some issues. For the time being the public access does not work.

Thank you
