Classification
Classification is a machine learning task where an AI system places information into predefined categories based on patterns learned from data.
Overview
Classification is a type of machine learning task where an AI system places information into predefined categories.
Rather than predicting a number, the model predicts which category something belongs to.
For example, a model may classify emails as spam or not spam, transactions as fraudulent or legitimate, or images as containing a dog or a cat.
The model learns from examples and then applies that knowledge to new information it has not seen before.
Why It Matters
Many real-world AI systems rely on classification.
It helps organizations automate decisions, organize information, detect risks, and improve efficiency.
Classification is one of the most common applications of machine learning.
Real-World Example
An email provider uses classification to automatically determine whether incoming messages should be placed in the inbox or spam folder.
