The above example looks awsome.
However, when executing, the output of the "Prediction" node is Nan for all of the predicted columns.
It seem to ocurr on two different KNIME installations,
( KNIME Analytics Platform 3.3.1.v201612192115
KNIME Deeplearning4J Integration (64bit only) 3.3.0.v201612012034)
Also, re-installed the deep learning extension with no results
sorry for your troubles. I looked at the workflow and somehow the configuration of the used network and Learner got messed up. If you change the activation function of both Dense Layers to 'TanH' and set the Global Learning Rate of the Learner node to '0.01' it should work fine.
