Record Class DeterministicAnnealing.Options

java.lang.Object

java.lang.Record

smile.clustering.DeterministicAnnealing.Options

Record Components:

kmax - the maximum number of clusters.

alpha - the temperature T is decreasing as T = T * alpha. alpha has to be in (0, 1).

maxIter - the maximum number of iterations at each temperature.

tol - the tolerance of convergence test.

splitTol - the tolerance to split a cluster.

controller - the optional training controller.

Enclosing class:

Options

public Options(int kmax,
 double alpha,
 int maxIter)

Constructor.

Parameters:

kmax - the maximum number of clusters.

alpha - the temperature T is decreasing as T = T * alpha. alpha has to be in (0, 1).

maxIter - the maximum number of iterations at each temperature.

Method Details

toProperties

public Properties toProperties()

Returns the persistent set of hyperparameters.

Returns:

the persistent set.

of

public static DeterministicAnnealing.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 '=='.

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.

kmax

public int kmax()

Returns the value of the kmax record component.

Returns:

the value of the kmax record component

alpha

public double alpha()

Returns the value of the alpha record component.

Returns:

the value of the alpha 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

splitTol

public double splitTol()

Returns the value of the splitTol record component.

Returns:

the value of the splitTol record component

controller

public IterativeAlgorithmController<AlgoStatus> controller()

Returns the value of the controller record component.

Returns:

the value of the controller record component
