plot_shap_force

method plot_shap_force(models=None, rows="test", target=1, title=None, legend=None, figsize=(900, 300), filename=None, display=True, **kwargs)[source]

Plot SHAP's force plot.

Visualize the given SHAP values with an additive force layout. Note that by default this plot will render using javascript. For a regular figure use matplotlib=True (this option is only available when only a single sample is plotted). Read more about SHAP plots in the user guide.

Parameters

models: int, str, Model or None, default=None Model to plot. If None, all models are selected. Note that leaving the default option could raise an exception if there are multiple models. To avoid this, call the plot directly from a model, e.g., atom.lr.plot_shap_force(). rows: hashable, segment, sequence or dataframe, default="test" Selection of rows to plot. target: int, str or tuple, default=1 Class in the target column to target. For multioutput tasks, the value should be a tuple of the form (column, class). Note that for binary and multilabel tasks, the selected class is always the positive one. title: str, dict or None, default=None Title for the plot. If None, no title is shown. If str, text for the title. If dict, title configuration. legend: str, dict or None, default=None Do nothing. Implemented for continuity of the API. figsize: tuple or None, default=(900, 300) Figure's size in pixels, format as (x, y). filename: str, Path 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 png. If None, the plot is not saved. display: bool or None, default=True Whether to render the plot. If None, it returns the figure (only if matplotlib=True in kwargs). **kwargs Additional keyword arguments for shap.plots.force.

Returns

plt.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, random_state=1)
>>> atom.run("LR")
>>> atom.plot_shap_force(rows=-2, matplotlib=True, figsize=(1800, 300))
