method plot_rfecv(title=None, figsize=(10, 6), filename=None, display=True) [source]

Plot the RFECV results, i.e. the scores obtained by the estimator fitted on every subset of the dataset. Only available if RFECV was applied on the data.

If None, the title is left empty. figsize: tuple, optional (default=(10, 6)) Figure's size, format as (x, y). filename: str or None, optional (default=None) Name of the file.

fig: matplotlib.figure.Figure Plot object. Only returned if display=None.

Example

from atom import ATOMClassifier

atom = ATOMClassifier(X, y)
atom.feature_selection(strategy="RFECV", solver="LGB", scoring="precision")
atom.plot_rfecv()
