Member Function Documentation

virtual Linear* clone (   )  const [inline, virtual]
 

Create a new object by replicating itself.

Returns:
A pointer to the new copy.
The code for a derived class Derived is always 
 return new Derived(*this);
Though seemingly redundant, it helps to copy an object without knowing the real type of the object.

Implements Kernel.

Definition at line 74 of file kernel.h.

virtual Linear* create (   )  const [inline, virtual]
 

Create a new object using the default constructor.

The code for a derived class Derived is always 

 return new Derived();

Implements Kernel.

Definition at line 73 of file kernel.h.

virtual const id_t& id (   )  const [virtual]
 

Returns:
Class ID string (class name)

Implements Object.

virtual REAL operator() (  const Input &  a,
const Input &  b
)  const [inline, virtual]
 

The inner-product of two input vectors.

Implements Kernel.

Definition at line 76 of file kernel.h.

void set_params (  SVM_detail *   )  const [virtual]
 

In order to keep the SVM interface simple and avoid member functions specific to kernels (e.g., set_gamma()), we use Kernel to pass kernel parameters to SVM_detail.

Implements Kernel.
