Consider the hypothesis space defined over instances shown below, we characterize eac hypothesis (apple taste) by 4-tuples. Please hand trace the ID3 classifier to build a decisio tree, then predict the target value Taste=Sweet/Tart for the following instances: a) b) c) d) e) 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.
