Function Documentation

tpt_svm_sigmoid_init_f32()

void tpt_svm_sigmoid_init_f32	(	tpt_svm_sigmoid_f32_t *	aSVM,
		uint32_t	nbOfSupportVectors,
		uint32_t	vectorDimension,
		f32_t	intercept,
		const f32_t *	dualCoefficients,
		const f32_t *	supportVectors,
		const int32_t *	classes,
		f32_t	coef0,
		f32_t	gamma )

SVM sigmoid instance init function.

Classes are integer used as output of the function (instead of having -1, 1 as class values).

Parameters

[in]	aSVM	points to an instance of the rbf SVM structure.
[in]	nbOfSupportVectors	Number of support vectors
[in]	vectorDimension	Dimension of vector space
[in]	intercept	Intercept
[in]	dualCoefficients	Array of dual coefficients
[in]	supportVectors	Array of support vectors
[in]	classes	Array of 2 classes ID
[in]	coef0	coeff0 (scikit-learn terminology)
[in]	gamma	gamma (scikit-learn terminology)

Returns

none.

Classes are integer used as output of the function (instead of having -1, 1 as class values).
