FeatureSet to Model

Synopsis​

This Operator converts a feature set object into a Preprocessing Model. Feature set objects are objects which are usually generated by Automatic Feature Engineering.

Description​

The resulting object can be applied with a normal Apply Model operator. It may also be used in conjunction with Group Models. This allows you to use feature models in operators like Model Simulator.

Input​

exa​

The training exampleset.

fea​

The feature set object you want to convert.

Output​

mod​

The preprocessing model.

ori​

The original ExampleSet passed through.

Parameters​

Handle missings​

Indicates if missing and infinite values should be replaced by the average / mode of known values if they appear as a result of feature generation.

Keep originals​

Indicates if attributes in the data which are not part of the feature set should be still kept.

Originals special role​

Indicates if original attributes which are kept should get a special role instead of regular so that they are not used my machine learning operators.
