Computing other metrics
In addition to accuracy, let's also compute the F1 score of this new model to get a better picture of model performance.
A 70-30 train-test split has already been done for you, and all necessary modules have been imported.
This exercise is part of the course
Marketing Analytics: Predicting Customer Churn in Python
Exercise instructions
- Predict the labels of the test set.
- Print the F1 score.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Import f1_score
from sklearn.metrics import f1_score
# Instantiate the classifier
clf = RandomForestClassifier()
# Fit to the data
clf.fit(X_train, y_train)
# Predict the labels of the test set
y_pred = ____
# Print the F1 score
print(____)
