"Rules" Page

The Rules Output page is used to:

  • View the results of Rules Query
  • Load previously saved Rules
  • View, print and save Rules  reports
  • Edit created or loaded Rules

Page Controls

"Rules Output" page contains such buttons:

  • "Edit Rules..." button - press it to open "Edit Rules" dialog.
  • "Report on Rules..." button - shows the "Report" dialog.
  • "Clear Rules" button - clears the results of Decision Rules query, after asking for a confirmation.

 

The created or loaded Rules are displayed in the "Decision Rules by Classes" control. Rule details can be viewed in the "Rule Details" control. Brief Query information (such as number of Decision Rules for a class, number of defined and undefined Classes), is placed on the right side of the program page.

"Decision Rules by Classes" control

All Rules, created as a result of a Query, or loaded from file, are displayed in the "Decision Rules by Classes" control. The control allows to navigate between Classes and Rules, viewing Rules details. In case if there are no Decision Rules for a Class, the Class will be disabled.

Each Decision Rule is marked with a unique number, ID (the number is not a part of a Rule), for example:

  • "Rule # 1"

The details of the selected Rule are displayed in the "Rule Details" control:

  1. Rule number
  2. Number of cases (records) that are described by a Rule, for example:
  • "rule met in X cases"
  1. Rule length:
  •  "number of elements in the Rule: X"

And the Rule itself:

Note: if the element in the Rule is of Integer or Real type, it is followed with it's average value:

  • "(average X)"

In case if Rules are edited, all changes are displayed on the proram page.

Filtering and Sorting

You can filter rules by length. To do so just change "Min Elements Number" value. Rules with length less than input will not be displayed.

You also can sort rules by length, probability or cases. Just select the sorting method from "Sort by" list.
