Description

Entry point to create a dataset from the provided parameters.

API

Syntax

Buffer API

template<layout ObservationsLayout = layout::row_major,
  typename Type> dataset<ObservationsLayout,
  sycl::buffer<Type, 1>> make_dataset(std::int64_t n_dims,
  std::int64_t n_observations,
  sycl::buffer<Type, 1> observations,
  sycl::buffer<Type, 1> weights = {0},
  sycl::buffer<std::int64_t, 1> indices = {0});

USM API

template<layout ObservationsLayout = layout::row_major,
  typename Type> dataset<ObservationsLayout,
  Type*> make_dataset(std::int64_t n_dims,
  std::int64_t n_observations,
  Type* observations, Type* weights = nullptr,
  std::int64_t* indices = nullptr);

oneapi/mkl/stats.hpp

Template Parameters

`typename DataType`	Type of dataset. May be `float`, `double`.
`oneapi::mkl::stats::layout ObservationsLayout`	Layout of the observations matrix of the dataset. The specific values are as follows: `oneapi::mkl::stats::layout::row_majoroneapi::mkl::stats::layout::col_major`

Input Parameters

Name	Type	Description
n_dims	`std::int64_t`	The number of dimensions (variables)
n_observations	`std::int64_t`	The number of observations
observations	`sycl::buffer<Type, 1> / Type*`	Matrix of observations

Optional Input Parameters

Name	Type	Description
weights	`sycl::buffer<Type, 1> / Type*`	Array of weights of size n_observations. Elements of the arrays are non-negative numbers. If the parameter is not specified, each observation is assigned weight equal to 1.
indices	`sycl::buffer<std::int64_t, 1> / std::int64_t*`	Array of vector components that will be processed. Size of array is `n_dims`. If the parameter is not specified, all components of the random vector are processed.

Return Type

Buffer API

oneapi::mkl::stats::dataset<ObservationsLayout, sycl::buffer<Type, 1>>

Dataset holding specified parameters

USM API

oneapi::mkl::stats::dataset<ObservationsLayout, Type*>

Dataset holding specified parameters
