The function mapping definition usr_SVMSparse specifies the following variable substitutions:
  • AttributeColumn is substituted for AttributeNameColumn
  • LabelColumn is substituted for ResponseColumn
  • ValueColumn is substituted for AttributeValueColumn

If the parameter AttributeNameColumn is specified during function processing, AttributeColumn is substituted for function processing. Similarly, if ResponseColumn is specified during function processing, LabelColumn is used. If AttributeValueColumn is specified during function processing, ValueColumn is used.
