Please Answer the questions below with reference to the confusion matrix shown:
- A test sample assigned to which class is the one we accept with highest confidence? Justify your answer please.
- Suppose that you have a binary classifier for each pair of classes that has 95% accuracy. Which two classes would you target?
- For (b), what is the final accuracy of the reduced (3x3) confusion matrix combined with a high-accuracy binary (95%) classifier for these two targeted classes? How does this compare to the original accuracy?
