Help understanding the train trigger
Posted: Fri Nov 04, 2016 7:20 pm
Hi there,
I cannot seem to get the trainer working with data from a CSV file.
I am trying to get a LDA training working on a CSV dataset from Emotiv. I have written a python script to read the emotiv csv and to convert it to a csv readable by openvibe. At the same time the script creates a stimulation file with time and duration parameters for each stimulation.
These stimulations are numbered (in this case 6 to 11) and each number corresponds to a mental command.
I cannot find out what stimulation the Classifier trainer needs to train. Here is an example of my stimulation csv:
Time (s),Identifier,Duration
72.902000,10,5.511000
83.743000,7,5.120000
96.436000,10,5.033000
106.074000,8,4.557000
119.392000,6,5.002000
............
.............
228.951000,6,5.291000
238.378000,8,5.096000
............
What do I need to add to correctly trigger the Training Classifier?
More specifically
[*]Does it require a something like a OVTK_StimulationId_Train at the beginning of the training file?
[*]Or does it require a stimulation that is simultaneous with the mental command tag?
[*]Or does it require a stimulation at the end after all the epochs have been sent through?
At the same time are there specific stimulations that I need to add at the beginning and end of the files to start and end the scenario?
Your help would be greatly appreciated.
