Indicate normalized RMSE error to stop neural network training.
A neural network calculation is stopped if RMSE error is less than value
of this keyword.The RMSE is defined as SQRT(SUM{(Ycalc-Yexp)^2}/n),
where Ycalc is calculated, Yexp is normalized
target value, and SUM is over n values. The Ycalc
values are calculated by simple average over all neural network predictions
in the ENSEMBLE. The termination of program
is done if RMSE error calculated for the learning set is less than LIMIT.
The default value is {0.0001}.
