Itemsets

Rules are calculated from itemsets. The Itemsets tab displays information about the itemsets.

If an attribute is a nested column, then the full name is displayed as COLUMN_ NAME.SUBNAME. For example, GENDER.MALE. If the attribute is a normal column, then just the column name is displayed.

Itemsets have Support. Each itemset contains one or more items.

• Sort Itemsets: Sort By specifies the order of itemsets. You can sort itemsets by:

  • ID

  • Number of Items

  • Support in Ascending Order

  • Support in Descending Order

  By default, itemset is sorted by Support in Descending order. For more sort options, click More. To change the sort order, make changes and then click Query.

• Filter Itemsets

• View Itemset details. Click the itemset to view the details.

The Itemsets tab displays the following information:

• Available Itemsets: The total number of itemsets in the model.

• Itemsets Retrieved: The number of itemsets retrieved by the query. That is, the number of itemsets retrieved subject to filtering.

• Itemset Content: For maximum information, select all three—Name, Subname, and Value. You can select a few characteristics from the menu.

To see details of a itemset, click the itemset and examine Rule Details.
