Question

Consider the hypothesis space defined over instances shown below, we characterize each

hypothesis (apple taste) by 4-tuples. Please hand trace the ID3 classifier to build a decision

tree, then predict the target value Taste=Sweet/Tart for the following instances:

a) <Red, High, Some, No>

b) <Red, Low, Some, Yes>

c) <Yellow, Low, Some, No>

d) <Green, High, None, No>

e) <Green, Mid, Some, Yes>

Now suppose the actual taste of the five apples above are actually “Sweet, Sweet,

Sweet, Tart, Tart”, what is the accuracy of the decision tree? Please show all the steps

and include the corresponding confusion matrix for accuracy calculation.
