👉 In the context of computer science, a classifier is a type of machine learning model that can be used to classify data into distinct categories or classes. It takes as input an array of training examples (or samples) and outputs a decision on whether each sample belongs to one of the classes. The output of the classifier is typically a binary value (0 or 1), with '1' indicating that the class should be selected for the sample, and '0' indicating that it should not be classified
