Create a new object by replicating itself.
return new Derived(*this);
Implements Kernel. |
|
Create a new object using the default constructor. The code for a derived class Derived is always return new Derived(); Implements Kernel. |
|
Implements Object. |

The inner-product of two input vectors.

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. Definition at line 163 of file svm.cpp. References Sigmoid::coef0, and Sigmoid::gamma. |
