Data to Weights

Synopsis

This operator simply generates an attribute weights vector with weight 1.0 for each input attribute.

Description

The Data to Weights operator creates a newattribute weights IOObjectfrom the given ExampleSet. The result is a vector of attribute weights containing the weight 1.0 for each attribute of the input ExampleSet.

Input

example set

This input port expects an ExampleSet. It is output of the Retrieve operator in the attached Example Process.

Output

weights

This port delivers the weights of the attributes with respect to the label attribute.

example set

The ExampleSet that was given as input is passed without changing to the output through this port. This is usually used to reuse the same ExampleSet in further operators or to view the ExampleSet in the Results Workspace.

Parameters

Normalize weights

This parameter indicates if the calculated weights should be normalized or not. If set to true, all weights are normalized in range from 0 to 1.

Sort weights

This parameter indicates if the attributes should be sorted according to their weights in the results. If this parameter is set to true, the order of the sorting is specified using the排序方向parameter.

Sort direction

This parameter is only available when thesort weightsparameter is set to true. This parameter specifies the sorting order of the attributes according to their weights.
