Method Details

toProperties

public Properties toProperties()

Returns the persistent set of hyperparameters including

• smile.cart.split_rule
• smile.cart.max_depth
• smile.cart.max_nodes
• smile.cart.node_size

Returns:

the persistent set.

of

public static DecisionTree.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.

Returns:

the value of the rule record component

maxDepth

public int maxDepth()

Returns the value of the maxDepth record component.

Returns:

the value of the maxDepth record component

maxNodes

public int maxNodes()

Returns the value of the maxNodes record component.

Returns:

the value of the maxNodes record component

nodeSize

public int nodeSize()

Returns the value of the nodeSize record component.

Returns:

the value of the nodeSize record component
