Classification
Definition
Classification is a type of supervised machine learning task where the goal is to predict a categorical output label. The model learns to assign a class label to an input example.
Why It Matters
Classification is used for problems like spam detection, image recognition, and medical diagnosis, where you need to assign an item to a predefined category.
Contextual Example
Determining whether an email is "spam" or "not spam" is a classification problem. The output is a discrete category.
Common Misunderstandings
- It is one of the two main types of supervised learning, the other being regression.
- Logistic regression, despite its name, is a classification algorithm.
