Chapter 10 Creating Neural Networks 281<br />

Overview of Neural Networks<br />

The Model Launch<br />

Use the Model Launch dialog to specify the validation method, the structure of the hidden layer, whether to<br />

use gradient boosting, <strong>and</strong> other fitting options.<br />

Fitting Options<br />

Select the method that you want to use for model validation. For details, see<br />

“Validation Method” on page 282.<br />

Note: The st<strong>and</strong>ard edition of JMP uses only the TanH activation function,<br />

<strong>and</strong> can fit only neural networks with one hidden layer.<br />

Specify the number of hidden nodes of each type in each layer. For details,<br />

see “Hidden Layer Structure” on page 283.<br />

Specify options for gradient boosting. For details, see “Boosting” on<br />

page 284.<br />

Specify options for variable transformation <strong>and</strong> model fitting. For details, see<br />

“Fitting Options” on page 285.
