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; WebLinear classifiers classify data into labels based on a linear combination of input features. Therefore, these classifiers separate data using a line or plane or a hyperplane (a plane in more than...
