For which target variable are results plotted?

I am using nntrainingtool for training a nn model. I have 2 scalar target variables, just name them O2 and CO2. Say, I have a network structure of 4-10-2. And, there are several plotting buttons in the dialog window, namely, Performance, Error Histogram, and Regression. I guess (maybe I am wrong) those are plotted based on the averaged values of errors of those two variables. But I want to be sure.

Thanks in advance.

Hi Ferhat ,

Yes if you have two output varibales , then the MSE will be

MSE = (|op1 - targ1|^2 + |op2 - targ2|^2 ) / 2

Thank you very much.
