mvpa2.clfs.warehouse.SigmoidLSKernel

class mvpa2.clfs.warehouse.SigmoidLSKernel(**kwargs)

Sigmoid kernel: K(a,b) = tanh(gamma*a*b.T + coef0)

Methods

add_conversion(typename, methodfull, methodraw)	Adds methods to the Kernel class for new conversions :Parameters: typename : string Describes kernel type methodfull : function Method which converts to the new kernel object class methodraw : function Method which returns a raw kernel ..
as_ls()
as_np()	Converts this kernel to a Numpy-based representation
as_raw_ls()
as_raw_np()
cleanup()	Wipe out internal representation
compute(*args, **kwargs)
computed(*args, **kwargs)	Compute kernel and return self
reset()

Initialize instance of SigmoidLSKernel

Parameters:

gamma :

Gamma multiplying parameter for SigmoidKernel. (Default: 1)

coef0 :

Offset inside tanh. (Default: 1)
