Question 31

+3 marksNumerical answer

In the given block of code, the Iris dataset having shape (150,4) has been loaded for model training. What do you think will be the output of the code given below?

python
from sklearn.datasets import load_iris
from sklearn.tree import DecisionTreeClassifier
from sklearn.model_selection import train_test_split
X,y = load_iris(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(max_features=2,
                             max_depth = 6,
                             min_samples_split = 2,
                             min_samples_leaf = 3,
                             random_state = 81 )


clf.fit(X_train, y_train)
print(clf.n_features_in_)
Show answer
