Constructor Detail

Trainer

public Trainer()

Constructor. The dimensionality of mapped space will be k - 1, where k is the number of classes of data. The default tolerance to covariance matrix singularity is 1E-4.

Method Detail

setDimension

public FLD.Trainer setDimension(int L)

Sets the dimensionality of mapped space.

Parameters:

L - the dimensionality of mapped space.

setTolerance

public FLD.Trainer setTolerance(double tol)

Sets covariance matrix singular tolerance.

Parameters:

tol - a tolerance to decide if a covariance matrix is singular. The trainer will reject variables whose variance is less than tol².

train

public FLD train(double[][] x,
                 int[] y)

Description copied from class: ClassifierTrainer

Learns a classifier with given training data.

Specified by:

train in class ClassifierTrainer<double[]>

Parameters:

x - the training instances.

y - the training labels.

Returns:

a trained classifier.
