Quiz · What Machine Learning Is · lesson 7 of 9Quiz — classification or regressionHow do you decide whether a task is classification or regression?[A]By the model's name: anything called a regression, logistic regression included, solves a regression task, and anything called a classifier solves a classification task, whatever values the target column actually holds in the data.[B]By the number of features: with one input feature the task is regression, a line drawn through the points, and with several features it becomes classification, since the feature space splits into regions.[C]By the target's data type: a numeric target, including class ids stored as 0, 1 and 2, is always a regression task, and only a text target such as "cat" or "dog" makes the task a classification one.[D]By the target, not the model: a target that is a category, even one stored as 0, 1, 2, makes it classification, and a continuous number such as a price makes it regression.
