Enum Constant Detail

NNDSVD

public static final NMFactorization.Init NNDSVD

Non-negative double singular value decomposition (Boutsidis and Gallopoulos). Deterministic. If the requested number of factors exceeds min(m,n), RANDOM is used instead.

RANDOM

public static final NMFactorization.Init RANDOM

Random values uniformly distributed within the range of the entries of V.

Method Detail

values

public static NMFactorization.Init[] 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 (NMFactorization.Init c : NMFactorization.Init.values())
    System.out.println(c);

Returns:

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

valueOf

public static NMFactorization.Init valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null
