Question 5

+3 marksWritten answer

An ML team wants to predict whether an email is spam or not by using some classification models. Therefore, the team defines three binary features where, = Presence of suspicious keywords (1 = present, 0 = absent)• = Whether the sender is unknown (1 = unknown, 0 = known)• = Whether the email contains a link (1 = yes, 0 = no)• The team collects the following dataset from previously classified emails:

The model makes a prediction using the rule : and

Compute the average loss on this dataset. Enter your answer correct to one decimal place.
