WitrynaIn classification, we saw that increasing the depth of the tree allowed us to get more complex decision boundaries. Let’s check the effect of increasing the depth in a regression setting: tree = DecisionTreeRegressor(max_depth=3) tree.fit(data_train, target_train) target_predicted = tree.predict(data_test) WitrynaThe basic dtreeviz usage recipe is: Import dtreeviz and your decision tree library. Acquire and load data into memory. Train a classifier or regressor model using your decision tree library. Obtain a dtreeviz adaptor model using. viz_model = dtreeviz.model (your_trained_model,...) Call dtreeviz functions, such as.
