I attach below my workflow for a regression using feedforward dl4j regression.
With the workflow, I attach the 2 csv files for the features and the 12 outputs.
It is straightforward to do the prediction but I am not sure how to evaluate and to visualise the performance of the regression as the numeric scorer allows me to choose only one output.
Is there a node suitable to evaluate the multitarget problem?
Here is the link for the workflow and the csv files.
