- Class Summary
  Class | Description
  --- | ---
  CachedKernel | Base class for RBFKernel and PolyKernel that implements a simple LRU.
  CheckKernel | Class for examining the capabilities and finding problems with kernels.
  Kernel | Abstract kernel.
  KernelEvaluation | Class for evaluating Kernels.
  NormalizedPolyKernel | The normalized polynomial kernel. K(x,y) = <x,y>/sqrt(<x,x><y,y>) where <x,y> = PolyKernel(x,y) Valid options are:
  PolyKernel | The polynomial kernel : K(x, y) = <x, y>^p or K(x, y) = (<x, y>+1)^p Valid options are:
  PrecomputedKernelMatrixKernel | This kernel is based on a static kernel matrix that is read from a file.
  Puk | The Pearson VII function-based universal kernel. For more information see: B.
  RBFKernel | The RBF kernel : K(x, y) = exp(-gamma*(x-y)^2) Valid options are:
  RegOptimizer | Base class implementation for learning algorithm of SMOreg Valid options are:
  RegSMO | Implementation of SMO for support vector regression as described in : A.J.
  RegSMOImproved | Learn SVM for regression using SMO with Shevade, Keerthi, et al.
  SMOset | Stores a set of integer of a given size.
  StringKernel | Implementation of the subsequence kernel (SSK) as described in [1] and of the subsequence kernel with lambda pruning (SSK-LP) as described in [2]. For more information, see Huma Lodhi, Craig Saunders, John Shawe-Taylor, Nello Cristianini, Christopher J.
