Member Function Documentation

float64_t compute	(	int32_t	idx_a,
		int32_t	idx_b
	)			`[protected, virtual]`

compute kernel for specific feature vectors corresponding to [idx_a] of left-side and [idx_b] of right-side

Parameters:

	idx_a	left-side index
	idx_b	right-side index

Returns:: kernel value

Implements CKernel.

Definition at line 61 of file InverseMultiQuadricKernel.cpp.

float64_t get_coef ( )

getter for coef parameter

Returns:: kernel parameter coefficient

Definition at line 83 of file InverseMultiQuadricKernel.h.

virtual EFeatureClass get_feature_class ( ) [virtual]

Returns:: class of features

Implements CKernel.

Definition at line 73 of file InverseMultiQuadricKernel.h.

virtual EFeatureType get_feature_type ( ) [virtual]

Returns:: type of features

Implements CKernel.

Definition at line 68 of file InverseMultiQuadricKernel.h.

virtual EKernelType get_kernel_type ( ) [virtual]

Returns:: kernel type

Implements CKernel.

Definition at line 63 of file InverseMultiQuadricKernel.h.

virtual const char* get_name ( void ) const [virtual]

Returns:: name of kernel

Implements CSGObject.

Definition at line 78 of file InverseMultiQuadricKernel.h.

bool init	(	CFeatures *	l,
		CFeatures *	r
	)			`[virtual]`

initialize kernel with features

Parameters:

	l	features left-side
	r	features right-side

Returns:: true if successful

Reimplemented from CKernel.

void load_serializable_post ( void ) throw (ShogunException) [protected, virtual]

Can (optionally) be overridden to post-initialize some member variables which are not PARAMETER::ADD'ed. Make sure that at first the overridden method BASE_CLASS::LOAD_SERIALIZABLE_POST is called.

Exceptions:

ShogunException

Will be thrown if an error occurres.

void set_coef ( float64_t value )

setter for coef parameter

Parameters:

value

kernel parameter coefficient
