plot_hyperparameter_importance

method plot_hyperparameter_importance(models=None, metric=0, show=None, title=None, legend=None, figsize=None, filename=None, display=True)[source]
Plot a model's hyperparameter importance.

The hyperparameter importance are calculated using the fANOVA importance evaluator. The sum of importances for all parameters (per model) is 1. This plot is only available for models that ran hyperparameter tuning.

Parametersmodels: int, str, Model, slice, sequence or None, default=None
Models to plot. If None, all models that used hyperparameter tuning are selected.

metric: int or str, default=0
Metric to plot (only for multi-metric runs).

show: int or None, default=None
Number of hyperparameters (ordered by importance) to show. None to show all.

title: str, dict or None, default=None
Title for the plot.

legend: str, dict or None, default=None
Legend for the plot. See the user guide for an extended description of the choices.

  • If None: No legend is shown.
  • If str: Location where to show the legend.
  • If dict: Legend configuration.

figsize: tuple or None, default=None
Figure's size in pixels, format as (x, y). If None, it adapts the size to the number of hyperparameters shown.

filename: str or None, default=None
Save the plot using this name. Use "auto" for automatic naming. The type of the file depends on the provided name (.html, .png, .pdf, etc...). If filename has no file type, the plot is saved as html. If None, the plot is not saved.

display: bool or None, default=True
Whether to render the plot. If None, it returns the figure.

Returnsgo.Figure or None
Plot object. Only returned if display=None.

Example

>>> from atom import ATOMClassifier
>>> from sklearn.datasets import load_breast_cancer

>>> X, y = load_breast_cancer(return_X_y=True, as_frame=True)

>>> atom = ATOMClassifier(X, y)
>>> atom.run(["LR", "RF"], n_trials=15)
>>> atom.plot_hyperparameter_importance()
