(5 marks) Consider a problem with a single real-valued feature ( x ). For any ( a<b ), consider the threshold classifiers

(5 marks) Consider a problem with a single real-valued feature r. For any a a), c(x) = [(x < b), and c3(x) = I(x < +), where the indicator function I(-) takes value +1 if its argument is true, and -1 otherwise. What is the set of real numbers classified as positive by f(x) = I(0.1c3(x) - c(x) - c(x) > 0)? If f(r) a threshold classifier? Justify your answer.
