Question 19

+4 marksOne correct option

The following code produces an output of 0.9125. How is the output expected to change if we increase the max_depth value?:

python
from sklearn.datasets import load_wine
from sklearn.tree import DecisionTreeClassifier
from sklearn.model_selection import train_test_split
X,y = load_wine(as_frame = True, return_X_y = True)


X_train,X_test,y_train,y_test = train_test_split(X,
                                                 y,
                                                 test_size = 0.10,
                                                 random_state = 12)


clf = DecisionTreeClassifier(max_depth = 2,
                             min_samples_split = 2,
                             min_samples_leaf=3,
                             random_state = 81)


clf.fit(X_train, y_train)
print(clf.score(X_train, y_train))
  1. A

    Output score is likely to increase.

  2. B

    Output score is likely to decrease.

  3. C

    Output score may increase or decrease.

  4. D

    Output score will remain the same.

Show answer
