The Neural Network training method may be invoked from the Excel formula bar with the following function calls:

=mdNeuralNet_Train(Parameters as Range, TrainingData as Range, Optional TestData as Range = Nothing)

Invoking the function with no arguments will print Help text associated with the model, including a link to this page.

An example image below shows the selection of the input parameters and model results in the Excel interface:

The Neural Network processing method may be invoked from the Excel formula bar with the following function calls:

=mdNeuralNet_Process(NetworkDefinition as Range, X as Range)

Invoking the function with no arguments will print Help text associated with the model, including a link to this page.
