使用C ++的typedef向量

Question

I'm using dlib to implement an algorithm, so far I was using a single kernel doing lake this:

The class in charge of the clustering:

template <
    typename kernel_type
    >
class kalog : public noncopyable
{
 public:
    kalog (
        const kernel_type& kernel_
    ):
       kernel(kernel_)
    {
    }
 private:
    kernel_type kernel;
}

The main:

typedef matrix<double,2,1> sample_type;
typedef radial_basis_kernel<sample_type> kernel_type;
kalog<kernel_type> my_kalog(kernel_type(0.1));

What I would like is to handle multiple kernel, but those ones could be different (radial_basis_kernel, polynomial_kernel, ...)

How, can I manage to provide my class a list of different type of kernel? any idea?

Answer 1

Keep

typedef radial_basis_kernel<sample_type> kernel_type;

and then

kernel_type kernel1;
kernel_type kernel2;
std::vector<kernel_type> kernels;
kernels.push_back(kernel1);
kernels.push_back(kernel2);

So you have:

• Types
  • kernel_type as a typedef of radial_basis_kernel<sample_type>
  • std::vector<kernel_type>
• Objects
  • kernel1 of type kernel_type
  • kernel2 of type kernel_type
  • kernels of type std::vector<kernel_type>
