A SignatureAttribute object describes the input expected to a model. This is automatically produced as part of the model.
It indicates not only the basic Attribute properties, but also how outliers and missing values were handled for model build.
This is potentially duplicate information from the MiningFunctionSettings, but must be provided since MiningFunctionSettings
are optional.
If an attribute was normalized or discretized automatically by the Data Mining System, the specific details are provided in
the SignatureAttribute object. The user is not expected to use this information to preprocess the data in any way. The Data
Mining System uses this information to automatically preprocess data, if required.
