Question 27

+3 marksOne correct option

For the following block of code, we get the output as 0.9875. How would the output change if we decrease 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 = 6,
                             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 will definitely increase.

  2. B

    Output score will definitely decrease.

  3. C

    Output score may decrease or remain the same.

  4. D

    Code will throw an error because max_depth can’t be less than 6.

Show answer

Correct answer

  • C

    Output score may decrease or remain the same.
