The input-output dataset
========================

The :class:`.IODataset` proposes two particular group names,
namely :attr:`~.IODataset.INPUT_GROUP` and :attr:`~.IODataset.OUTPUT_GROUP`.
This particular :class:`.Dataset` is useful
for supervised machine learning and sensitivity analysis.

.. code-block:: default

    from __future__ import annotations

    from gemseo.datasets.io_dataset import IODataset








.. GENERATED FROM PYTHON SOURCE LINES 35-37

First,
we instantiate the :class:`.IODataset`:

.. GENERATED FROM PYTHON SOURCE LINES 37-39

.. code-block:: default

    dataset = IODataset()








.. GENERATED FROM PYTHON SOURCE LINES 40-44

and add some input and output variables
using the methods
:meth:`~.IODataset.add_input_variable` and :meth:`~.IODataset.add_output_variable`
that are based on :meth:`.Dataset.add_variable`:

.. GENERATED FROM PYTHON SOURCE LINES 44-47

.. code-block:: default

    dataset.add_input_variable("a", [[1.0, 2.0], [4.0, 5.0]])
    dataset.add_input_variable("b", [[3.0], [6.0]])
    dataset.add_output_variable("c", [[-1.0], [-2.0]])







.. GENERATED FROM PYTHON SOURCE LINES 48-49

as well as another variable:

.. GENERATED FROM PYTHON SOURCE LINES 49-52

.. code-block:: default

    dataset.add_variable("x", [[10.0], [20.0]])
    dataset

We could also do the same with the methods

    dataset = IODataset()

    )
    dataset.add_output_group([[-1.0], [-2.0]], ["c"])
    dataset.add_variable("x", [[10.0], [20.0]])

Then,
we can easily access the names of the input and output variables:

.. GENERATED FROM PYTHON SOURCE LINES 66-67

.. code-block:: default

    dataset.input_names, dataset.output_names




.. rst-class:: sphx-glr-script-out

 .. code-block:: none


    (['a', 'b'], ['c'])



.. GENERATED FROM PYTHON SOURCE LINES 68-69

and those of all variables:

.. GENERATED FROM PYTHON SOURCE LINES 69-71

.. code-block:: default

    dataset.variable_names





.. rst-class:: sphx-glr-script-out

 .. code-block:: none


    ['a', 'b', 'c', 'x']



.. GENERATED FROM PYTHON SOURCE LINES 72-73

The :class:`.IODataset` provides also the number of samples:

.. GENERATED FROM PYTHON SOURCE LINES 73-74

.. code-block:: default

    dataset.n_samples




.. rst-class:: sphx-glr-script-out

 .. code-block:: none


    2



.. GENERATED FROM PYTHON SOURCE LINES 75-76

and the samples:

.. GENERATED FROM PYTHON SOURCE LINES 76-78

.. code-block:: default

    dataset.samples





.. rst-class:: sphx-glr-script-out

 .. code-block:: none


    [0, 1]



.. GENERATED FROM PYTHON SOURCE LINES 79-81

Lastly,
we can get the input data as an :class:`.IODataset` view:

.. code-block:: default

    dataset.input_dataset
