public class OraFeatureExtractionSettings

extends oracle.dmt.jdm.base.OraBuildSettings

OraFeatureExtractionSettings object encapsulates the following build settings specific to feature extraction.

• Number of features to control the maximum number of features that can be extracted by the model. The default value is computed by the DME using heuristics that depend on the number of columns and rows in the input data.
