Binary classifier

A binary classifier is a type of artificial intelligence tool that makes decisions by sorting things into exactly two categories, like determining whether an email is spam or not spam. It works by analyzing features of the input (such as words in an email) and learning patterns from examples to predict which of the two groups something belongs to. Binary classifiers are fundamental in machine learning and appear everywhere in science and everyday life, from medical diagnosis systems that classify patients as healthy or diseased to quality control systems in manufacturing.
