Enum Constant Details

RFF

public static final FfCiContinuous.FeatureType RFF

Represents the Random Fourier Features (RFF) feature generation method.

RFF is a technique used to approximate the Radial Basis Function (RBF) kernel by applying random projections. This method provides an efficient way to compute kernel features for large-scale machine learning tasks.

ORF

public static final FfCiContinuous.FeatureType ORF

Represents the Orthogonal Random Features (ORF) feature generation method.

ORF is a technique used to approximate the Radial Basis Function (RBF) kernel by applying random projections with orthogonality constraints. This method ensures more structured and efficient projections, improving the quality of the kernel approximation while maintaining computational efficiency.

Method Details

values

public static FfCiContinuous.FeatureType[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static FfCiContinuous.FeatureType valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
