Question 28

+3 marksOne correct option

Consider the following block of code and mark the correct option.

python
from sklearn.datasets import load_breast_cancer
from sklearn.tree import DecisionTreeClassifier
from sklearn.model_selection import train_test_split
X,y = load_breast_cancer(as_frame = True,
                         return_X_y = True)
X_train,X_test,y_train,y_test = train_test_split(X,
                                                 y,
                                                 test_size = 0.2,
                                                 random_state = 1)
clf = DecisionTreeClassifier(min_samples_split = 5,
                             random_state = 5)
clf.fit(X_train, y_train)
print(clf.score(X_test, y_test))
