Labeling
Domain: Data & Datasets
🎯 Motivation
Adding correct answers to training examples. Supervised learning needs labeled data.
📋 Concrete Example
Labeling: image of a cat -> label: cat. Image of a dog -> label: dog. 10,000 images labeled = dataset ready for supervised training.
🔗 Analogy
A teacher marking answer keys on practice exams - each question gets the correct answer. Labeling marks the correct answer for each training example.
