I am using NARNET to predict multi-step ahead values for temperature data for my laser set operation.
For standardized data (mean = 0 and Var = 1), performance values are following:
OpenloopMSEperformance = 5.451431363178139e-05
OpenloopPERFORMperformance = 5.505768944105006e-05
ClosedloopMSEperformance = 1.043409861314658e-04
ClosedloopPERFORMperformance = 1.053810133096861e-04
However, when I am predicting multi-step ahead values, for next 30 signals, results are really bad.
What can be the reason?
