shap.force_plot¶
-
shap.
force_plot
(base_value, shap_values=None, features=None, feature_names=None, out_names=None, link='identity', plot_cmap='RdBu', matplotlib=False, show=True, figsize=20, 3, ordering_keys=None, ordering_keys_time_format=None, text_rotation=0)¶ Visualize the given SHAP values with an additive force layout.
- Parameters
- base_valuefloat
This is the reference value that the feature contributions start from. For SHAP values it should be the value of explainer.expected_value.
- shap_valuesnumpy.array
Matrix of SHAP values (# features) or (# samples x # features). If this is a 1D array then a single force plot will be drawn, if it is a 2D array then a stacked force plot will be drawn.
- featuresnumpy.array
Matrix of feature values (# features) or (# samples x # features). This provides the values of all the features, and should be the same shape as the shap_values argument.
- feature_nameslist
List of feature names (# features).
- out_namesstr
The name of the output of the model (plural to support multi-output plotting in the future).
- link“identity” or “logit”
The transformation used when drawing the tick mark labels. Using logit will change log-odds numbers into probabilities.
- matplotlibbool
Whether to use the default Javascript output, or the (less developed) matplotlib output. Using matplotlib can be helpful in scenarios where rendering Javascript/HTML is inconvenient.
