Constructor Detail

GradientDescentApproximator.Factory

public GradientDescentApproximator.Factory(GradientDescentApproximator.Constraints constraints,
                                   boolean ignoreBias)

Parameters:

constraints - As in GradientDescentApproximator constructor

ignoreBias - As in GradientDescentApproximator constructor

Method Detail

getApproximator

public LinearApproximator getApproximator(float[][] evalPoints,
                                 float[][] values)

Specified by:

getApproximator in interface ApproximatorFactory

Parameters:

evalPoints - Points at which component functions are evaluated. These should usually be uniformly distributed, because the sum of error at these points is treated as an integral over the domain of interest.

values - The values of component functions at the evalPoints. The first dimension makes up the list of functions, and the second the values of these functions at each evaluation point.

Returns:

A LinearApproximator that can be used to approximate new Functions as a wieghted sum of the given components.

clone

public ApproximatorFactory clone()
                          throws java.lang.CloneNotSupportedException

Specified by:

clone in interface ApproximatorFactory

Overrides:

clone in class java.lang.Object

Returns:

Valid clone

Throws:

java.lang.CloneNotSupportedException - if clone can't be made
