public class VectorElementThresholdCategorizer extends AbstractThresholdBinaryCategorizer<Vectorizable>
VectorElementThresholdCategorizer class implements a
BinaryCategorizer that categorizes an input vector by applying a
threshold to an element in a the vector. The threshold is a
greater-than-or-equal threshold.

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 AbstractCloneableSerializableprotected double evaluateWithoutThreshold(Vectorizable input)
