Binary classification is the task of classifying the elements of a set into two groups (each called class) on the basis of a classification rule. Typical binary classification problems include: • Medical testing to determine if a patient has certain disease or not; • Quality control in industry, deciding whether a specification has been met; http://www.csce.uark.edu/~lz006/course/2024spring/7-linear%20classifier.pdf
