Enclosing class:

NHERD

public static enum NHERD.CovMode
extends Enum<NHERD.CovMode>

Sets what form of covariance matrix to use

Enum Constant Summary

Enum Constants

Enum Constant and Description
DROP Standard diagonal method, only the diagonal values get updated by dropping the other terms.
EXACT Creates the diagonal by solving the derivative with respect to the specific objective function of NHERD
FULL Use the full covariance matrix
PROJECT Creates the diagonal by dropping the terms of the inverse of the covariance matrix that is used to perform the update.

Enum Constant Detail

FULL

public static final NHERD.CovMode FULL

Use the full covariance matrix

DROP

public static final NHERD.CovMode DROP

Standard diagonal method, only the diagonal values get updated by dropping the other terms.

PROJECT

public static final NHERD.CovMode PROJECT

Creates the diagonal by dropping the terms of the inverse of the covariance matrix that is used to perform the update. This authors suggest this is usually the best for diagonal covariance matrices from empirical testing.

EXACT

public static final NHERD.CovMode EXACT

Creates the diagonal by solving the derivative with respect to the specific objective function of NHERD

Method Detail

values

public static NHERD.CovMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (NHERD.CovMode c : NHERD.CovMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static NHERD.CovMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
