"Force neural net output value"

nav

Hello, is it possible to force the neural net output value to positive value? My problem is that with a training set with positive and negative attributes but an only positive label attribute, the neural net classifier sometimes predicts wrong negative values. Thanks a lot to all.

Hi,
you could simply apply a postprocessing step. You could easily configure the Generate Attribute operator to derive a column that has a minimum of 0 for example. Then you could set the role of this new column to "prediction" and it will be used as new prediction in a following performance estimator.
