multiple target neural network in sas viya

Is it possible to have more than one target variable specified for Neural Networks in SAS Viya? Proc NNet and the neuralNet action in Proc CAS do not seem to allow this.

Hello,

According to the doc of PROC NNET, you can indeed specify only one target variable (or none in which case an auto-encoder is trained).

But PROC NEURAL and PROC HPNEURAL accept multiple variables in the TARGET statement.

The 2 targets are fit simultaneously, in a single model.

Also, in Enterprise Miner (SAS 9.4), ... in your metadata, ... you could assign the TARGET role to multiple variables. A single NN-model was then created to explain / predict all targets (dependent vars).

I never tried the latter in Model Studio (SAS Viya successor to EMiner for ML-projects). You can try it ... assigning TARGET role to 2 variables.

By the way, you can still run PROC HPNEURAL in SAS Viya. It will run in SPRE-engine, but multi-threaded.
