Constructor Detail

Trainer

public Trainer(smile.math.kernel.MercerKernel<T> kernel,
               double lambda)

Constructor.

Parameters:

kernel - the Mercer kernel.

lambda - the shrinkage/regularization parameter.

Method Detail

train

public GaussianProcessRegression<T> train(T[] x,
                                          double[] y)

Description copied from class: RegressionTrainer

Learns a regression model with given training data.

Specified by:

train in class RegressionTrainer<T>

Parameters:

x - the training instances.

y - the training response values.

Returns:

a trained regression model.

train

public GaussianProcessRegression<T> train(T[] x,
                                          double[] y,
                                          T[] t)

Learns a Gaussian Process with given subset of regressors.

Parameters:

x - training samples.

y - training labels in [0, k), where k is the number of classes.

t - the inducing input, which are pre-selected or inducing samples acting as active set of regressors. Commonly, these can be chosen as the centers of k-means clustering.

Returns:

a trained Gaussian Process.
