What is the difference between classification and regression?
Updated May 15, 2026
Short answer
Classification predicts categories, while regression predicts continuous values.
Deep explanation
Classification assigns inputs to discrete labels, whereas regression estimates numerical outputs. Both are supervised learning but differ in output space and evaluation metrics.
Real-world example
Predicting whether a loan will default (classification) vs predicting loan amount (regression).
Common mistakes
- Using regression metrics for classification problems.
Follow-up questions
- Can classification output probabilities?
