Detailed Description

Calculates the C-SVM kernel using the nd_range formulation and the radial basis functions kernel function.

Currently only single GPU execution is supported.

Template Parameters

T	the type of the data

Construct a new device kernel calculating the C-SVM kernel using the radial basis functions C-SVM kernel.

Parameters

[in]	cgh	`sycl::handler` used to allocate the local memory
[in]	q	the `q` vector
[out]	ret	the result vector
[in]	d	the right-hand side of the equation
[in]	data_d	the one-dimension data matrix
[in]	QA_cost	he bottom right matrix entry multiplied by cost
[in]	cost	1 / the cost parameter in the C-SVM
[in]	num_rows	the number of columns in the data matrix
[in]	num_cols	the number of rows in the data matrix
[in]	add	denotes whether the values are added or subtracted from the result vector
[in]	gamma	the gamma parameter used in the rbf kernel function

template<typename T >

void plssvm::sycl::detail::nd_range_device_kernel_rbf< T >::operator() ( ::sycl::nd_item< 2 > nd_idx ) const

inline

Function call operator overload performing the actual calculation.

Parameters

[in] nd_idx the sycl::nd_item identifying an instance of the functor executing at each point in a sycl::range
