Re: Classification error

Not yet, I am still trying to see the output of my classifier. I am trying using VRPN as you told me, but I still have no results there.

Re: Classification error

Yes but I understand the classifier procesor has two aoutputs, one of them is a values output (the green one) and the other one is the labels output, which shows stimulations (the purple one). There is where I set the stimulations listener.

Re: Classification error

Actually the scenario is working right, I can see the feedback, and this means the classifier processor is working. But what I want to do is seeing its response as a signal or in some other way than the blue bar.

Re: Classification error

Hi all! I am still having troubles trying to "see" in some way the output of my classifier processor. I have used the stimulation listener and, setting the log level to "information" I get stimulations all the time (I suppose this is correct, since the classifier processor should work all the time),...

Re: Classification error

Hi Uahmed, I'm sorry I couldn't answer before. I have been really busy and couldn't check the files you sent me, but now I will look at them. Anyway, I found a big mistake in the scenarios I was working with, and that was the issue I was having with the feedback. The problem was that I was using a ....

Re: Classification error

Hi Uahmed, I hope you get better soon!

You say I have a wrong number of input channels and the location of the cfg file, but where? What settings should I correct? During the acquisition I only use 14 channel, and don't check the box of the gyroscope channels, so I am not using them.

Thanks!

Re: Classification error

Re: Classification error

Ok, so it's more complicated than I thought... Actually my problem is that I am not getting feedback during the online session and I suspect it is because the classifier is not doing anything. This is why I used the signal display conected to the classifier processor. Before I used the stimulation l...
