Supervised Learning
Definition
The machine learning task of learning a function that maps an input to an output based on example input-output pairs.
Deep Dive
Supervised learning is a foundational machine learning task where an algorithm learns to map input data to an output based on a dataset of labeled examples. The "supervision" comes from the fact that each input observation in the training data is paired with its correct or desired output label. The model's objective is to learn the underlying function that best describes this relationship between inputs and outputs, enabling it to make accurate predictions or classifications on new, unseen data that it has not encountered before.
Examples & Use Cases
- 1Training an email filter to classify incoming messages as either "spam" or "not spam"
- 2Predicting house prices based on features like location, size, and number of bedrooms using historical sales data
- 3Developing an image recognition system that identifies specific objects (e.g., cats, dogs, cars) in photographs
