negative output from neural networks

I am getting negative predictions (continuous) from a neural network model that has been trained on data that only contains positive values or zeros (no nulls).

Is there a setting that can limit the lower end of the output range to zero?

Hello

There is no algorithm setting that can limit the outputs range. However, you could use a different query construct to get this result. Assuming that your predictable column is labeled [Petal Length], your query could look like:

SELECT VBA FROM [Model] PREDICTION JOIN ...

The [IIF] function is part of a set of built-in custom functions and it is defined as

IIF( boolean_condition, true_value, false_value)

Hope this helps
