Building Multiple Models at the Same Time Takes Longer than Expected (277371)

WORKAROUND

If you want to build more than one model at the same time, do it through a script rather than the MMC. If you have a model in the building process and you want to stop the process, right-click the model line, and then click Stop.

The following Microsoft Visual Basic code demonstrates how to use script to build multiple models:

Dim dBuildParams As Commerce.Dictionary
Set dBuildParams = Server.CreateObject("Commerce.Dictionary")
 
dBuildParams("ModelType") = 0
dBuildParams("ComplexityPenalty") = 75
dBuildParams("InputAttributeFraction") = 0.5
dBuildParams("MeasuredAccuracyMaxPredictions") = 10
dBuildParams("MeasuredAccuracySampleFraction") = 0.2
dBuildParams("MinimumCasesToSplit") = 10
dBuildParams("OutputAttributeFraction") = .5
dBuildParams("SampleSize") = 15,000

Dim oPersistXML As IPersistXML
Set oPersistXML = dBuildParams

Dim sXMLBuildParams As String
sXMLBuildParams = oPersistXML.SaveXML(0)

Set oPersistXML = Nothing
Set dBuildParams = Nothing

Dim oPredModelBuilder As Commerce.PredictorModelBuilder
Set oPredModelBuilder = _
Server.CreateObject("Commerce.PredictorModelBuilder")

Dim lBuildID(5) As Long 
Dim I As Integer
For I=0 To 5
	lBuildID(I) = oPredModelBuilder.Start(sDWConnect, "", _
	 "PurchaseCfg1", "Purchase" & I, sXMLBuildParams, True)
Next I

Set oPersistXML = Nothing
Set dBuildParams = Nothing
Set oPredModelBuilder = Nothing
