Imagination detection right hand and left hand
Posted: Thu Jul 05, 2018 8:22 pm
Hello everyone,
I have registered the movement imagination of the right and left hand with an 8-electrode g.Nautilus device, and I am trying to be able to detect the classes online.
The first thing I did was to record the data using a protocol where the task to be performed would be shown randomly and the user for 10 seconds imagined to move the right or left hand, the electrodes used to position them in C3, Cz and C4, well done an offline scenario to train an LDA classifier and the results are good, in the order of 70%, but when I use that classifier to classify new data, it gives me pure chance, I do not know what I'm doing wrong.
Attached my two scenarios the first is the offline treatment and the second to process the new data in a pseudo online.
thank you very much.
