Consider the traffic accident data set shown in the following table.
Let Crash Severity be the class label. Show the key steps for the following tasks.
(a) Using information gain as the attribute selection measure, construct the first level of the decision tree.
(b) If gain ratio is used as the attribute selection measure, will the first level of the decision tree be different from above?
(c) Given a traffic accident with the values Good, Sober, None, and Yes for the attributes Weather Condition, Drivers Condition, Traffic Violation, and Seat Belt, respectively, how would a nave Bayesian classifier determine whether Crash Severity would be Minor or Major?
