plot_rfecv

method plot_rfecv(title=None, legend=None, figsize=(900, 600), filename=None, display=True)[source]
Plot the rfecv results.

Plot the scores obtained by the estimator fitted on every subset of the dataset. Only available when feature selection was applied with strategy="rfecv".

Parameterstitle: 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, default=(900, 600)
Figure's size in pixels, format as (x, y).

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.

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.feature_selection("rfecv", solver="Tree")
>>> atom.plot_rfecv()
