Indicate if neural network models should be saved.The option on request the C++ program to return file models
that can be further retrieved to predict new data. This file should be
copy-pasted inside of the corresponding window in the Data parameters
window of the program. This will automatically requests the C++ program
to use the saved model to predict new data (the value of the MODELS
keyword will be increased by 2). User should verify that number input variables
is the same as it was saved. A detailed explanation of the models
file is available here.
