mvpa2.kernels.sg.PrecomputedSGKernel

class mvpa2.kernels.sg.PrecomputedSGKernel(matrix=None, **kwargs)

A kernel which is precomputed from a numpy array or a Shogun kernel

Attributes

descr

Description of the object if any

Methods

add_conversion(typename, methodfull, methodraw)	Adds methods to the Kernel class for new conversions
as_ls(kernel)
as_np()	Converts this kernel to a Numpy-based representation
as_raw_ls(kernel)
as_raw_np()	Directly return this kernel as a numpy array
as_raw_sg()
as_sg()
cleanup()	Wipe out internal representation
compute(\*args, \*\*kwargs)	‘Compute’ PrecomputedSGKernel – no actual “computation” is done
computed(\*args, \*\*kwargs)	Compute kernel and return self
reset()

Initialize PrecomputedSGKernel

Parameters:

matrix : SGKernel or Kernel or ndarray

Kernel matrix to be used
