Re: Unable to get root node error when using classifier

I am not sure if the classifier is meaningful so I copied and pasted it below. I did run the example scenarios and they worked. Thank you for your help. <OpenViBE-Scenario> <Creator>OpenViBE</Creator> <CreatorVersion>1.3.0</CreatorVersion> <Boxes> <Box> <Identifier>(0x0000104d, 0x00004d02)</Identifi...

Unable to get root node error when using classifier

I have set up the classifier so that it creates the configuration in the trainer and accesses it in the processor but it says that it is unable to get the root node from the file I created in the trainer. Does this file need to be preexisting? I currently have it writing to a file I did not create b...

Simple dsp question

Hello, I have a question regarding the simple dsp box. I want to divide two signal averages to get the alpha/theta ratio and I am unsure how to do this. I have the two signal averages and have tried to assign each of them a variable via a simple dsp box and then divide the two using another simple d...

Confusion with classifier

Hello! I am relatively new to OpenViBE and could use some help with using the classifier trainer and processor. I understand that the two boxes are used in conjunction, but I am confused on how to implement them. For my project I want to have the classifier classify based on two features, theta rela...

Parkinson's detection using OpenVibe

Hello, I am new to OpenVibe and could use some help with my project. I am looking to use EEG signals to detect Parkinson's disease. I believe that I will need to use a Random Forest as my classifier, and one of the features should be alpha to theta ratio in the central left region, and another shoul...
