The machine learning task of learning a function that maps an input to an output based on example input-output pairs. It infers a function from '' consisting of a set of training examples. In supervised learning, each example is a pair consisting of an input object (typically a vector) and a desired output value (also called the supervisory signal''). A supervised learning algorithm analyzes the training data and produces an inferred function, which can be used for mapping new examples. An optimal scenario will allow for the algorithm to correctly determine the class labels for unseen instance

A way of training machine learning systems for a specific application. In a training phase, an AI system is fed labelled data. The system trains from the input data, and the resulting model is then tested to see if it can correctly apply labels to new unlabelled data (such as if it can correctly label unlabelled pictures of cats and dogs accordingly). This type of learning is useful when it is clear what is being searched for, such as identifying spam mail.

is a type of AI, or machine learning, that operates on data. With supervised learning, we have a specific question in mind, like 'Does this photo have a cat in it?' To answer this question with a computer, we collect lots of photos, many with cats and many without. This is our data, which we can use to train our algorithm. The most important part of supervised learning is that we understand the task fully, and can thus label each image ourselves, 'Has cat' or 'No cat.' We can then feed this labeled training data through a supervised learning algorithm, which learns to apply this same label to new images.
