SANN - Automated Network Search (ANS)

Select the Automated network search (ANS) option button on the Quick tab of the SANN - Data selection dialog box and click OK to display the SANN - Automated Network Search (ANS) dialog box, which contains three tabs: Quick, MLP activation functions, and Weight decay. Use the options on these tabs to configure the settings of the automated network search algorithm.

Active neural networks. The grid in the Active neural networks group box provides a quick view of the networks you have. Note that if you have not trained any networks or have no currently active networks, this grid will be empty.

Train. Click the Train button to build (or train) networks according to the specifications made on the tabs of this dialog. While the networks are being trained, the Neural networks training in progress dialog will be displayed. This dialog provides summary details of networks as they are created. When the requested number of networks has been trained, the SANN - Results dialog is displayed.

Go to results. Click this button to display the SANN - Results dialog box without performing additional training. Note that if the Active neural networks grid is empty, this button will not be available.

Save networks. Click this button to display a drop-down list containing the following commands:

PMML script. Select PMML script to display the Save PMML file dialog box, which contains options to store the active networks for future use. Note that this dialog will be displayed only when the Active neural networks grid contains networks. Stored PMML networks can be opened by clicking the Load network files button in the SANN - New Analysis/Deployment Startup Panel.

C/C++ language. Select C/C++ language to display the Save C file dialog box, which contains options to store the active networks for future use.

SAS code. Select SAS code to display the Save SAS file dialog, which contains options to save deployment code for the created model as SAS code (a .sas file). See also, Rules for SAS Variable Names.

Deployment to STATISTICA Enterprise. Select this command to deploy the results as an Analysis Configuration in STATISTICA Enterprise. Note that appropriately formatted data must be available in a STATISTICA Enterprise Data Configuration before the results can be deployed to an Analysis Configuration.

Data statistics. Click the Data statistics button to generate a spreadsheet containing the mean, standard deviation, minimum value and maximum value for each continuous variable in the analysis. These data statistics will be broken down by each sample (training, testing, and validation) and also reported for the overall data set.

Summary. Click the Summary button to generate a spreadsheet containing the summary details listed in the Active neural networks grid box. Note that if the Active neural networks grid is empty, this button will not be available.

Cancel. Click the Cancel button to exit the Automated Network Search and return to the SANN - Data selection dialog. This action will result in the loss of the existing models, and you will be notified to that effect unless you have already saved the networks in PMML or C/C++ format (see the description of Save networks for more details).

Options. Click the Options button to display the Options menu.
