Observe thoroughly the restaurant_dat.csv dataset and the corresponding decision tree shown in the below figure. Using the entropy E and information gain IG, show by hand calculation how the attributes such as Patrons (Pat), Hungry (Hun), Type (Type), and Fri/Sat (FriSat) are chosen as a root node or decision nodes respectively. Based on your comprehensive E and IG calculations, could we also get other decision tree representations? Please provide analysis on this matter
