-    """Visualizes decision boundaries of a binary classifier.
-
-    Works by sampling from the feature space where the classifier's uncertainty
-    if greater than > 0.5 and projecting these point to 2D space.
-
-    Useful for measuring model (decision boundary) complexity, visualizing
-    regions where the model falters, and to determine whether any over or
-    underfitting occured.
-
-    Should only be called with a fitted **binary** classifer (otherwise an error is
-    thrown). Please note this function fits variations of the model on the
-    training set when called.
-
-    Arguments:
-        model: (clf) Takes in a fitted binary classifier.
-        X_train: (arr) Training set features.
-        y_train: (arr) Training set labels.
-
-    Returns:
-        None: To see plots, go to your W&B run page then expand the 'media' tab
-              under 'auto visualizations'.
