The following table describes the elements that are included in the XSD schema for MiningModel. Those elements common to all major objects are described in section 2.2.4.2.2.1.

Element

Read-Only

Default value

Description

Algorithm

[Required]

The protocol does not require any particular algorithms to be supported, and each server developer can support whichever algorithms he or she chooses to support.<102>

LastProcessed

Yes

The date and time when the mining model was last processed.

AlgorithmParameters

Empty

A collection of objects of type AlgorithmParameter. The allowed parameters are different depending on the algorithm.

AllowDrillThrough

False

When true, indicates that drillthrough is allowed; otherwise, false.

Translations

Empty

A collection of Translation objects.

Columns

Empty

A collection of objects of type MiningModelColumn.

State

Yes

Represents the processing state of the partition. Values include:

  • Processed

  • Unprocessed

FoldingParameters

Empty

An object of type FoldingParameters. Describes a fold (a partition of the training data) to be used for training this mining model. Used only as part of the multifold cross-validation procedure.<103>

Filter

Empty

The DMX filter statement to be applied to training data for models that are trained only on a part of a structure's data. An empty string or missing element implies no filter.<104>

MiningModelPermissions

Empty

A collection of MiningModelPermission objects.

Language

Empty

The language to use by default.

Collation

Empty

The collation sequence to use.
