oracle.dmt.jdm.featureextraction.OraFeatureExtractionModel
Feature Extraction creates a new set of features based on the original data. The new features extraction let you describe the data with a number of features far smaller than the number of original dimensions (attributes). A feature is a combination of attributes that is of special interest and captures important characteristics of the data.
OraFeatureExtractionModel
object encapsulates the details of extracted features from the traning data.
