a) What are the variables used in this anlysis?

What is the name of the algorithm used for learning the Bayesian network structure?

b) In the learnt Bayesian network provided in Figure 4 (in the paper), is Injury type independent of Sex given the knowledge about Seat belt, licence type and vehicle type? Explain.

c) In Figure 5 (in the paper), explain what the probabilities shown for Injury Type means.

d) Read the section titled “Parameter learning in the road accident network” in that paper and find the following probabilities:

I. The probability of dead while wearing seat belt and driving a car, knowing that the driver has a diploma degree and a type 2 driving license

II. The probability of being not-injured while wearing seat belt and driving a car, knowing that the driver has a diploma degree and a type 2 driving license.

Hint
Computer"Bayesian networks are a type of probabilistic graphical model that represents a set of variables and their probabilistic dependencies using a directed acyclic graph. They are commonly used for modeling uncertain relationships among variables and making predictions or inferences based on available data. Bayesian networks have various real-world applications, including:Medical Diagnosis: Ba...
