Any update on this?

Thanks for the info. Can you kindly explain what non-linear activation function (Sigmoid, tanh, Relu etc.) is used in its implementation? And what if I have to change it to the one I want to use?

Thanks. Can you also please tell if there is any box setting for SWLDA and Intelligent Segmentation in OpenViBE or these both need to be coded as well?

Thanks for your reply. Now, I have used two CSV writers, and the stimulations obtained are: Time (s);Identifier;Duration 1.9942382813e+001;32769;0.0000000000e+000 however, it does not make sense to me. I am doing a P300 experiment and want to do some classifications out of the openViBE for which the...

I have .ov file of P300 signals acquired using the example scenario of P300. Now, I want to use it for classification, but there is no label in it. I have converted the .ov file to .csv and the file has the following format: Time (s);F4;T7;F8;T8;FP1;F7;FP2;F3;O1;O2;C4;P4;P3;Cz;Pz;C3;Sampling Rate wh...

I am using P300 xDAWN scenario. I have to experiment my results with different classifiers. However, the Classifier Trainer box has the options for LDA, SVM and Multi-layer Protection only. I have to apply Deep Learning algorithm here to the signals after applying xDAWN Spatial Filter. Is there any ...

My question is how to develop a nested matrix in OpenViBE for P300 scenario i.e. one of the cells in the matrix is tied to another matrix which is displayed when this cell is selected by the user e.g. in menu based interface.
Please inform how this can be achieved using OpenViBE?
