method plot_roc(models=None, dataset="test", title=None, figsize=(10, 6), filename=None, display=True) [source]

Parameters:

dataset: str, optional (default="test")
Data set on which to calculate the metric. Options are "train", "test" or "both".

title: str or None, optional (default=None)
Plot's title. 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. Use "auto" for automatic naming. If None, the figure is not saved.

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

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


Example

from atom import ATOMClassifier
atom = ATOMClassifier(X, y)
atom.run(["LR", "RF", "LGB"], metric="roc_auc")
atom.plot_roc(filename="roc_curve")
