Adaptive Bayes Network Model Viewer

For a brief description of the ABN algorithm, see Adaptive Bayes Network Algorithm.

ABN is used to create classification models. For a brief description of classification models, see Classification.

Note: The Adaptive Bayes Network (ABN) algorithm is deprecated in Oracle Data Mining 11g. Oracle Data Miner does not support building ABN models; you can view ABN models created using the Oracle Data Mining 11g APIs. Use the Decision Tree algorithm to generate rules.

Menus

The following menus appear when the model is displayed in a new window:

Tabs

The model viewer has the following tabs:

Build Settings

This tab displays the Type of the model (Classification), the Algorithm used to build the model (Adaptive Bayes Network), the Target Attribute of the model, the Algorithm settings used to build the model, the Attributes used to build the model, and the Cost matrix (if present).

The Model Build Type determines the settings that are available. For example, the following is displayed for Single Feature Build:

For detailed information about ABN settings, including settings for all model types, see Adaptive Bayes Network Settings.

Attributes that are important to the model build process are displayed in a grid; the following information is displayed for each such attribute:

To save the attributes information as a text file, click the Save As icon (a yellow arrow above a graphic of a page) above the Attributes grid.

Prior Probabilities or a Cost Matrix may be generated during model build. Click either Prior Probabilities or Cost Matrix to view the values. For more information, see Priors or Costs.

Results

To see results, click the Results tab.

The tab contains a tree view of results. To view specific results, select the result, and click View. To delete results, select one or more results and click Delete.

Rules

Not all ABN models generate rules. If the Model Build Type is Single Feature, rules are generated, and a Rules tab is displayed. To see the rules, click the Rules tab.

The rules are listed in grid; the column headings in the grid are Rule Id, If (condition), Then (classification), Confidence,and Support.

To view a rule, select the Rule Id; the rule is displayed in the Rules area.

Data for an ABN model build is discretized (binned). If the bin table is available, Bin is available. Click Bin to use bin values in the rules; click Unbin to use unbinned values. The default is to use unbinned values.

To view the detailed display of a rule, select the rule; details are displayed in the area below the rules display.

Save Rules

To save the rules to a file, click the Save As icon (a yellow arrow above a graphic of a page) above the Rules grid.

Task

This tab describes the task used to build the model. It shows when the task ran, what input was used, and what output was created.
