Classification analysis is a supervised machine learning process for predicting a class or category of a given data point in a dataset. For example, it can determine whether an email is spam or not. Classification is for predicting discrete, categorical values, unlike regression analysis, which predicts continuous, numerical values. 7.5.0 introduces binary classification, which can label data points into two possible categories.
