Interface FeatureSelector

public interface FeatureSelector

FeatureSelector selects features that are accurate and of interest

Method Summary

int[]	getIndices() Returns the indices of the selected features (an index is between 0 and one less than the number of features).
float[][]	selectFeatures(float[][] data, int[] targets) Stores features from data and store any relevant values such as the dimensions of data and targets.
float[][]	selectFeaturesGivenIndices(float[][] data, int[] indices) Selects features using indices and returns the selected features.
void	setParameters(java.util.HashMap<java.lang.String,java.lang.String> para) Sets algorithm parameters from para

Method Detail

setParameters

void setParameters(java.util.HashMap<java.lang.String,java.lang.String> para)

Sets algorithm parameters from para

Parameters:

para - Each element of the hashmap holds a parameter name for its key and a its value is that of the parameter. The parameters should be the same as those in the algorithms.xml file.

selectFeatures

float[][] selectFeatures(float[][] data,
                         int[] targets)

Stores features from data and store any relevant values such as the dimensions of data and targets.

Parameters:

data - Two-dimensional array of extracted image data

targets - Array of the targets for the image

Returns:

Two-dimensional array of features that are selected

getIndices

int[] getIndices()

Returns the indices of the selected features (an index is between 0 and one less than the number of features).

Returns:

The indices of the selected features.

selectFeaturesGivenIndices

float[][] selectFeaturesGivenIndices(float[][] data,
                                     int[] indices)

Selects features using indices and returns the selected features.

Parameters:

data - Two-dimensional array of extracted image data

indices - Array of indices to the data columns

Returns:

Two-dimensional array of features that are selected
