        Scores on test set.

    score_name : str, default=None
        The name of the score used in `learning_curve`. It will override the name
        inferred from the `scoring` parameter. If `score` is `None`, we use `"Score"` if
        `negate_score` is `False` and `"Negative score"` otherwise. If `scoring` is a
        string or a callable, we infer the name. We replace `_` by spaces and capitalize
        the first letter. We remove `neg_` and replace it by `"Negative"` if
        `negate_score` is `False` or just remove it otherwise.

    Attributes
    ----------
    ax_ : matplotlib Axes
        Axes with the learning curve.

    figure_ : matplotlib Figure
        Figure containing the learning curve.

    errorbar_ : list of matplotlib Artist or None
        When the `std_display_style` is `"errorbar"`, this is a list of
        `matplotlib.container.ErrorbarContainer` objects. If another style is
        used, `errorbar_` is `None`.

    lines_ : list of matplotlib Artist or None
        When the `std_display_style` is `"fill_between"`, this is a list of
        `matplotlib.lines.Line2D` objects corresponding to the mean train and

        visualization.

        Parameters
        ----------
        estimator : object type that implements the "fit" and "predict" methods
            An object of that type which is cloned for each validation.

        X : array-like of shape (n_samples, n_features)
            Training data, where `n_samples` is the number of samples and
            `n_features` is the number of features.

        y : array-like of shape (n_samples,) or (n_samples, n_outputs) or None
            Target relative to X for classification or regression;
            None for unsupervised learning.

        groups : array-like of shape (n_samples,), default=None
            Group labels for the samples used while splitting the dataset into
            train/test set. Only used in conjunction with a "Group" :term:`cv`
            instance (e.g., :class:`GroupKFold`).

        train_sizes : array-like of shape (n_ticks,), \
                default=np.linspace(0.1, 1.0, 5)
            Relative or absolute numbers of training examples that will be used
            to generate the learning curve. If the dtype is float, it is
            regarded as a fraction of the maximum size of the training set
            (that is determined by the selected validation method), i.e. it has
            to be within (0, 1]. Otherwise it is interpreted as absolute sizes
            of the training sets. Note that for classification the number of
            samples usually have to be big enough to contain at least one
            sample from each class.

        cv : int, cross-validation generator or an iterable, default=None
            Determines the cross-validation splitting strategy.
            Possible inputs for cv are:

            - None, to use the default 5-fold cross validation,
            - int, to specify the number of folds in a `(Stratified)KFold`,
            - :term:`CV splitter`,
            - An iterable yielding (train, test) splits as arrays of indices.

            For int/None inputs, if the estimator is a classifier and `y` is
            either binary or multiclass,
            :class:`~sklearn.model_selection.StratifiedKFold` is used. In all
            other cases, :class:`~sklearn.model_selectionKFold` is used. These
            splitters are instantiated with `shuffle=False` so the splits will
            be the same across calls.

            Refer :ref:`User Guide <cross_validation>` for the various
            cross-validation strategies that can be used here.

        scoring : str or callable, default=None
            A string (see :ref:`scoring_parameter`) or
            a scorer callable object / function with signature
            `scorer(estimator, X, y)` (see :ref:`scoring`).

        exploit_incremental_learning : bool, default=False
            If the estimator supports incremental learning, this will be
            used to speed up fitting for different training set sizes.

        n_jobs : int, default=None
            Number of jobs to run in parallel. Training the estimator and
            computing the score are parallelized over the different training
            and test sets. `None` means 1 unless in a
            :obj:`joblib.parallel_backend` context. `-1` means using all
            processors. See :term:`Glossary <n_jobs>` for more details.

        pre_dispatch : int or str, default='all'
            Number of predispatched jobs for parallel execution (default is
            all). The option can reduce the allocated memory. The str can
            be an expression like '2*n_jobs'.

        verbose : int, default=0
            Controls the verbosity: the higher, the more messages.

        shuffle : bool, default=False
            Whether to shuffle training data before taking prefixes of it
            based on`train_sizes`.

        random_state : int, RandomState instance or None, default=None
            Used when `shuffle` is True. Pass an int for reproducible
            output across multiple function calls.
            See :term:`Glossary <random_state>`.

        error_score : 'raise' or numeric, default=np.nan
            Value to assign to the score if an error occurs in estimator
            fitting. If set to 'raise', the error is raised. If a numeric value
            is given, FitFailedWarning is raised.

        fit_params : dict, default=None
            Parameters to pass to the fit method of the estimator.

        ax : matplotlib Axes, default=None
            Axes object to plot on. If `None`, a new figure and axes is
            created.

        negate_score : bool, default=False
            Whether or not to negate the scores obtained through
            :func:`~sklearn.model_selection.learning_curve`. This is
            particularly useful when using the error denoted by `neg_*` in
            `scikit-learn`.

        score_name : str, default=None
            The name of the score used to decorate the y-axis of the plot. It will
            override the name inferred from the `scoring` parameter. If `score` is
            `None`, we use `"Score"` if `negate_score` is `False` and `"Negative score"`
            otherwise. If `scoring` is a string or a callable, we infer the name. We
            replace `_` by spaces and capitalize the first letter. We remove `neg_` and
            replace it by `"Negative"` if `negate_score` is
            `False` or just remove it otherwise.

        score_type : {"test", "train", "both"}, default="both"
            The type of score to plot. Can be one of `"test"`, `"train"`, or
            `"both"`.

        log_scale : bool, default="deprecated"
            Whether or not to use a logarithmic scale for the x-axis.

            .. deprecated:: 1.3
               `log_scale` is deprecated in 1.3 and will be removed in 1.5.
               Use `display.ax_.xscale` and `display.ax_.yscale` instead.

        std_display_style : {"errorbar", "fill_between"} or None, default="fill_between"
            The style used to display the score standard deviation around the
            mean score. If `None`, no representation of the standard deviation
            is displayed.

    Parameters
    ----------
    param_name : str
        Name of the parameter that has been varied.

    param_range : ndarray of shape (n_ticks,)
        The values of the parameter that have been evaluated.

    train_scores : ndarray of shape (n_ticks, n_cv_folds)
        Scores on training sets.

    test_scores : ndarray of shape (n_ticks, n_cv_folds)
        Scores on test set.

    score_name : str, default=None
        The name of the score used in `validation_curve`. It will override the name
        inferred from the `scoring` parameter. If `score` is `None`, we use `"Score"` if
        `negate_score` is `False` and `"Negative score"` otherwise. If `scoring` is a
        string or a callable, we infer the name. We replace `_` by spaces and capitalize
        the first letter. We remove `neg_` and replace it by `"Negative"` if
        `negate_score` is `False` or just remove it otherwise.

    Attributes
    ----------
    ax_ : matplotlib Axes
        Axes with the validation curve.

    figure_ : matplotlib Figure
        Figure containing the validation curve.

    errorbar_ : list of matplotlib Artist or None
        When the `std_display_style` is `"errorbar"`, this is a list of
        `matplotlib.container.ErrorbarContainer` objects. If another style is
        used, `errorbar_` is `None`.

    lines_ : list of matplotlib Artist or None
        When the `std_display_style` is `"fill_between"`, this is a list of
        `matplotlib.lines.Line2D` objects corresponding to the mean train and
        test scores. If another style is used, `line_` is `None`.

    fill_between_ : list of matplotlib Artist or None
        When the `std_display_style` is `"fill_between"`, this is a list of
        `matplotlib.collections.PolyCollection` objects. If another style is
        used, `fill_between_` is `None`.

        Parameters
        ----------
        estimator : object type that implements the "fit" and "predict" methods
            An object of that type which is cloned for each validation.

        X : array-like of shape (n_samples, n_features)
            Training data, where `n_samples` is the number of samples and
            `n_features` is the number of features.

        y : array-like of shape (n_samples,) or (n_samples, n_outputs) or None
            Target relative to X for classification or regression;
            None for unsupervised learning.

        param_name : str
            Name of the parameter that will be varied.

        param_range : array-like of shape (n_values,)
            The values of the parameter that will be evaluated.

        groups : array-like of shape (n_samples,), default=None
            Group labels for the samples used while splitting the dataset into
            train/test set. Only used in conjunction with a "Group" :term:`cv`
            instance (e.g., :class:`GroupKFold`).

        cv : int, cross-validation generator or an iterable, default=None
            Determines the cross-validation splitting strategy.
            Possible inputs for cv are:

            - None, to use the default 5-fold cross validation,
            - int, to specify the number of folds in a `(Stratified)KFold`,
            - :term:`CV splitter`,
            - An iterable yielding (train, test) splits as arrays of indices.

            For int/None inputs, if the estimator is a classifier and `y` is
            either binary or multiclass,
            :class:`~sklearn.model_selection.StratifiedKFold` is used. In all
            other cases, :class:`~sklearn.model_selectionKFold` is used. These
            splitters are instantiated with `shuffle=False` so the splits will
            be the same across calls.

            Refer :ref:`User Guide <cross_validation>` for the various
            cross-validation strategies that can be used here.

        scoring : str or callable, default=None
            A string (see :ref:`scoring_parameter`) or
            a scorer callable object / function with signature
            `scorer(estimator, X, y)` (see :ref:`scoring`).

        n_jobs : int, default=None
            Number of jobs to run in parallel. Training the estimator and
            computing the score are parallelized over the different training
            and test sets. `None` means 1 unless in a
            :obj:`joblib.parallel_backend` context. `-1` means using all
            processors. See :term:`Glossary <n_jobs>` for more details.

        pre_dispatch : int or str, default='all'
            Number of predispatched jobs for parallel execution (default is
            all). The option can reduce the allocated memory. The str can
            be an expression like '2*n_jobs'.

        verbose : int, default=0
            Controls the verbosity: the higher, the more messages.

        error_score : 'raise' or numeric, default=np.nan
            Value to assign to the score if an error occurs in estimator
            fitting. If set to 'raise', the error is raised. If a numeric value
            is given, FitFailedWarning is raised.

        fit_params : dict, default=None
            Parameters to pass to the fit method of the estimator.

        ax : matplotlib Axes, default=None
            Axes object to plot on. If `None`, a new figure and axes is
            created.

        negate_score : bool, default=False
            Whether or not to negate the scores obtained through
            :func:`~sklearn.model_selection.validation_curve`. This is
            particularly useful when using the error denoted by `neg_*` in
            `scikit-learn`.

        score_name : str, default=None
            The name of the score used to decorate the y-axis of the plot. It will
            override the name inferred from the `scoring` parameter. If `score` is
            `None`, we use `"Score"` if `negate_score` is `False` and `"Negative score"`
            otherwise. If `scoring` is a string or a callable, we infer the name. We
            replace `_` by spaces and capitalize the first letter. We remove `neg_` and
            replace it by `"Negative"` if `negate_score` is
            `False` or just remove it otherwise.

        score_type : {"test", "train", "both"}, default="both"
            The type of score to plot. Can be one of `"test"`, `"train"`, or
            `"both"`.

        std_display_style : {"errorbar", "fill_between"} or None, default="fill_between"
            The style used to display the score standard deviation around the
            mean score. If `None`, no representation of the standard deviation
            is displayed.

        line_kw : dict, default=None
            Additional keyword arguments passed to the `plt.plot` used to draw
            the mean score.

        fill_between_kw : dict, default=None
            Additional keyword arguments passed to the `plt.fill_between` used
            to draw the score standard deviation.

        errorbar_kw : dict, default=None
            Additional keyword arguments passed to the `plt.errorbar` used to
            draw mean score and standard deviation score.
