\subsection{Detailed Description}
\subsubsection*{template$<$typename Kernel\+Type$>$\newline
class mlpack\+::kernel\+::\+Kernel\+Traits$<$ Kernel\+Type $>$}

This is a template class that can provide information about various kernels. 

By default, this class will provide the weakest possible assumptions on kernels, and each kernel should override values as necessary. If a kernel doesn\textquotesingle{}t need to override a value, then there\textquotesingle{}s no need to write a \doxyref{Kernel\+Traits}{p.}{classmlpack_1_1kernel_1_1KernelTraits} specialization for that class.
