Record Class SpectralClustering.Options

java.lang.Object

java.lang.Record

smile.clustering.SpectralClustering.Options

Record Components:

k - the number of clusters.

l - the number of random samples for Nystrom approximation. Uses 0 to disable approximation.

sigma - the smooth/width parameter of Gaussian kernel, which is a somewhat sensitive parameter. To search for the best setting, one may pick the value that gives the tightest clusters (smallest distortion) in feature space.

maxIter - the maximum number of iterations.

tol - the tolerance of convergence test.

controller - the optional training controller.

Enclosing class:

SpectralClustering

public static record SpectralClustering.Options(int k, int l, double sigma, int maxIter, double tol, IterativeAlgorithmController<AlgoStatus> controller)
extends Record

sigma - the smooth/width parameter of Gaussian kernel.

maxIter - the maximum number of iterations.

Method Details

toProperties

public Properties toProperties()

Returns the persistent set of hyperparameters.

Returns:

the persistent set.

of

public static SpectralClustering.Options of(Properties props)

Returns the options from properties.

Parameters:

props - the hyperparameters.

Returns:

the options.

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

k

public int k()

Returns the value of the k record component.

Returns:

the value of the k record component

l

public int l()

Returns the value of the l record component.

Returns:

the value of the l record component

sigma

public double sigma()

Returns the value of the sigma record component.

Returns:

the value of the sigma record component

maxIter

public int maxIter()

Returns the value of the maxIter record component.

Returns:

the value of the maxIter record component

tol

public double tol()

Returns the value of the tol record component.

Returns:

the value of the tol record component

controller

public IterativeAlgorithmController<AlgoStatus> controller()

Returns the value of the controller record component.

Returns:

the value of the controller record component
