Interface GradientDescentApproximator.Constraints

All Superinterfaces:

java.lang.Cloneable, java.io.Serializable

All Known Implementing Classes:

GradientDescentApproximator.CoefficientsSameSign

Enclosing class:

GradientDescentApproximator

public static interface GradientDescentApproximator.Constraints
extends java.io.Serializable, java.lang.Cloneable

Enforces constraints on coefficients. TODO: should this be generalized to LinearApproximator?

Method Summary

Modifier and Type	Method and Description
GradientDescentApproximator.Constraints	clone()
boolean	correct(float[] coefficients)

Method Detail

correct

boolean correct(float[] coefficients)

Parameters:

coefficients - A set of coefficients which may violate constraints (they are altered as little as possible by this method so that they satisfy constraints after the call)

Returns:

True if all coefficients had to be corrected (no further improvement is possible in the attempted direction)

clone

GradientDescentApproximator.Constraints clone()
                                              throws java.lang.CloneNotSupportedException

Returns:

Valid clone

Throws:

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