Programming Interface
---------------------
All types and functions in this section are declared in the
``oneapi::dal::svm`` namespace and are available via inclusion of the
``oneapi/dal/algo/svm.hpp`` header file.

Method tags
~~~~~~~~~~~
.. onedal_tags_namespace:: oneapi::dal::svm::method

Task tags
~~~~~~~~~
.. onedal_tags_namespace:: oneapi::dal::svm::task

Model

--------------------------------
.. _svm_t_api_input:

Input
~~~~~
.. onedal_class:: oneapi::dal::svm::train_input


.. _svm_t_api_result:

Result

      | :expr:`input.labels.is_empty == false`
      | :expr:`input.labels.column_count == 1`
      | :expr:`input.data.row_count == input.labels.row_count`

.. _svm_i_api:

Inference :expr:`infer(...)`
----------------------------
.. _svm_i_api_input:

Input
