org.encog.ml.importance.AbstractFeatureImportance

org.encog.ml.importance.NeuralFeatureImportanceCalc

All Implemented Interfaces:

FeatureImportance

public class NeuralFeatureImportanceCalc
extends AbstractFeatureImportance

A feature ranking algorithm based on the weights of a neural network. This algorithm can only be used for neural networks, and it cannot calculate importance relative to a new dataset.

Method Detail

performRanking

public void performRanking()

Perform the ranking, without using a specific training set. Not all ranking algorithms support this.

performRanking

public void performRanking(MLDataSet theDataset)

Perform the ranking, using a specific training set. Not all ranking algorithms can make use of a dataset.

Parameters:

theDataset - The dataset.
