riscv_svm_sigmoid_init_f16()

RISCV_DSP_ATTRIBUTE void riscv_svm_sigmoid_init_f16	(	riscv_svm_sigmoid_instance_f16 *	S,
		uint32_t	nbOfSupportVectors,
		uint32_t	vectorDimension,
		float16_t	intercept,
		const float16_t *	dualCoefficients,
		const float16_t *	supportVectors,
		const int32_t *	classes,
		float16_t	coef0,
		float16_t	gamma
	)

[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)
