InputType - The type of the input to the Kernel. For example, Vector.@CodeReview(reviewer="Kevin R. Dixon", date="2009-07-08", changesNeeded=false, comments={"Made clone call super.clone.","Looks fine otherwise."}) public class KernelDistanceMetric<InputType> extends DefaultKernelContainer<InputType> implements Metric<InputType>
KernelDistanceMetric class implements a distance metric that
utilizes an underlying Kernel for computing the distance. The
distance is computed as:
kernel| Constructor and Description |
|---|
KernelDistanceMetric()
Creates a new instance of KernelDistanceMetric.
|
KernelDistanceMetric(Kernel<? super InputType> kernel)
Creates a new instance of KernelDistanceMetric using the given kernel.
|
KernelDistanceMetric(KernelDistanceMetric<InputType> other)
Creates a new copy of a KernelDistanceMetric.

| Modifier and Type | Method and Description |

clone()
This makes public the clone method on the
Object class and

evaluate(InputType first,
InputType second)
Computes the distance between the two given objects using the Kernel it
was given.

AbstractCloneableSerializableObject class and
removes the exception that it throws. Its default behavior is to
automatically create a clone of the exact type of object that the
clone is called on and to copy all primitives but to keep all references,
which means it is a shallow copy.
Extensions of this class may want to override this method (but call
super.clone() to implement a "smart copy". That is, to target
the most common use case for creating a copy of the object. Because of
the default behavior being a shallow copy, extending classes only need
to handle fields that need to have a deeper copy (or those that need to
be reset). Some of the methods in ObjectUtil may be helpful in
implementing a custom clone method.
Note: The contract of this method is that you must use
super.clone() as the basis for your implementation.clone in interface CloneableSerializableclone in class DefaultKernelContainer<InputType>public double evaluate(InputType first, InputType second)
