Q$5[20$ Marks$]$

In this question, you cannot use XLMiner.

We have the following Bayesian Belief Network.

Suppose that there is a new patient. We know that

$(1)$ he has acute pancreatitis

$(2)$ he has pneumonia

$(3)$ his result of white blood cell is high

We would like to know whether he is likely to have systemic inflammation reaction.

$($a$)$ Please use Bayesian Belief Network classifier with the use of Bayesian Belief Network to predict

whether he is likely to have systemic inflammation reaction.

$($b$)$ Although Bayesian Belief Network classifier does not have an independent assumption among all

attributes $($compared with the na$$ve Bayesian classifier$),$ what are the disadvantages of this classifier?
