ML.INSPECT.DECISION_BOUNDARY

Extracts the decision boundary contour points for a classifier and input data X.

Syntax

ML.INSPECT.DECISION_BOUNDARY(model, X, response_method, mesh_step, class_pair, feature_indices, other_features_values, margin)

Arguments

Name Type Default Description
model object Fitted classifier with predict or decision_function method
X object numpy array or pandas DataFrame of predictors (n_samples, n_features)
response_method str "predict" predict or decision_function
mesh_step float 0.05 step size for the mesh grid
class_pair list[int] [0, 1] tuple of two ints (for multiclass decision_function), e.g., (0, 1) or (1, 0)
feature_indices tuple[int, int] (0, 1) tuple of two ints indicating which features to use for boundary calculation
other_features_values dict[int, float] None dict or None. If dict, keys are feature indices and values are the values to use for other features
margin float 0.1 Positional argument 8
