DiscretizationMethod Element (ASSL)

  • Άρθρο

Defines the method to be used for discretization.

Syntax

  
<DimensionAttribute> <!-- or ScalarMiningStructureColumn -->  
   ...  
   <DiscretizationMethod>...</DiscretizationMethod>  
   ...  
</DimensionAttribute>

Element Characteristics

Characteristic Description
Data type and length String (enumeration)
Default value None
Cardinality 0-1: Optional element that can occur once and only once.

Element Relationships

Relationship Element
Parent elements DimensionAttribute, ScalarMiningStructureColumn
Child elements None

Remarks

The value of the DiscretizationMethod element determines how values for the DimensionAttribute or ScalarMiningStructureColumn are discretized, or organized into a specific set of groups.

The value of this element is limited to one of the strings in the following table.

Value Description
Automatic Equivalent to the AUTOMATIC discretization method for mining structure columns.
EqualAreas Equivalent to the EQUAL_AREAS discretization method for mining structure columns.
Clusters Equivalent to the CLUSTERS discretization method for mining structure columns.
Thresholds Equivalent to the THRESHOLDS discretization method for mining structure columns.
EqualRanges Equivalent to the EQUAL_RANGES discretization method for mining structure columns.

The enumeration corresponding to the allowed values for DiscretizationMethod in the Analysis Management Objects (AMO) object model is DiscretizationMethod.
