@CodeReview(reviewer="Kevin R. Dixon", date="2009-07-08", changesNeeded=false, comments={"Made clone call super.clone.","Looks fine otherwise."}) public class LinearKernel extends AbstractCloneableSerializable implements Kernel<Vectorizable>
LinearKernel class implements the most basic kernel: it just
does the actual inner product between two vectors.| Constructor and Description |
|---|
LinearKernel()
Creates a new instance of LinearKernel.

| Modifier and Type | Method and Description |
|---|---|
LinearKernel |
clone()
This makes public the clone method on the
Object class and
removes the exception that it throws. |
double |
evaluate(Vectorizable x,
Vectorizable y)
Evaluates the linear kernel by taking the inner product of the two
vectors.
|
static LinearKernel |
getInstance()
Gets the single instance of this class because it has no internal data.

public LinearKernel clone()
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 AbstractCloneableSerializablepublic double evaluate(Vectorizable x, Vectorizable y)
evaluate in interface Kernel<Vectorizable>x - The first vector.y - The second vector.
