All Implemented Interfaces:

Iterable<DataCell>, DataRow

final class BasisFunctionFilterRow
extends Object
implements DataRow

Inner class to separate an data input row into a new row which are the first n-1 double cells and returns the class label.

Constructor Summary

BasisFunctionFilterRow(BasisFunctionLearnerTable model, DataRow row, int[] dataColumns, int[] classColumns, String[] classColumnNames, BasisFunctionLearnerTable.MissingValueReplacementFunction missing)
Create new basisfunction input data row with data and class columns.
