Methods

method %GetCategoryInfo(Output pCategories) as %Status

Returns all categories added so far: pCategories(n) = $lb([name], [record count])

method %GetRecordCount(Output pSC As %Status) as %Integer

method %LoadCategoriesFromColumn(pExpression As %String) as %Status

Loads categories based on the value of the supplied SQL expression. pExpression should either be the (SQL) name of a column on TableName, or a valid SQL expression that can be selected from that table (aliased as if required "t").

method %TestClassifier(pTestSet As %RawString = "", Output pResult, Output pAccuracy As %Double, pCategorySpec As %String = "", pVerbose As %Boolean = 0) as %Status

Utility method to batch-test the classifier against a test set pTestSet, which can be supplied as a valid SQL WHERE clause to be queried against TableName. Per-record results are returned through pResult:
pResult(n) = $lb([record ID], [actual category], [predicted category])

pAccuracy will contain the raw accuracy (# of records predicted correctly) of the current model. Use %iKnow.Classificaton.Utils for more advanced model testing.

If the current model's category options were added through %AddCategory() without providing an appropriate category specification (again through a SQL WHERE clause), rather than through a call to %LoadCategoriesFromColumn (which sets CategoryColumn), supply a column name or SQL expression through pCategorySpec where the actual category values to test against can be found.
