Save Proc Neural parameter estimates in a file and re-use them to make predictions

[NN1]

Hello,

I would like to save Proc Neural parameter estimates in a file and re-use them to make predictions.  For example, first run:

proc neural data=out_training dmdbcat=out.cat_training random=789;
 input PRI_jet_all_pt / level=nominal id=i;
 target label / level=nominal id=o;
 train;
 save outest=out.est;
 run;

This saves the parameter estimates in out.est.  Is there a way to run Proc Neural again on different datasets to make predictions, i.e. with the USE statement, e.g.

proc neural data=out_training dmdbcat=out.cat_training;
USE out.est;
score out=out outfit=fit;
run;

When I run the above I receive the following error ("ERROR: Will not be able to continue"):

proc neural data=out_training dmdbcat=out.cat_training;
 use out.est;
 There are no layers in the network.
 ERROR: Will not be able to continue.
 score out=out outfit=fit;
 run;

Any ideas?

Hi, have you tried using data step scorecode (code statement)? Proc neural produces scorecode so you can use this scorecode in a scoring process with data step.

It worked! Thanks for your help!
