Import helper for PyMVPA kernels/similarities and alike
Classes
CachedKernel([kernel]) | Kernel which caches all data to avoid duplicate computation This kernel is very useful for any analysis which will retrain or repredict the same data multiple times, as this kernel will avoid recalculating the kernel function. |
CustomKernel([kernelfunc]) | Custom Kernel defined by an arbitrary function .. |
Kernel(*args, **kwargs) | Abstract class which calculates a kernel function between datasets Each instance has an internal representation self._k which might be of a different form depending on the intended use. |
NumpyKernel(*args, **kwargs) | A Kernel object with internal representation as a 2d numpy array .. |
PrecomputedKernel([matrix]) | Precomputed matrix .. |
