Supervised learning, also known as supervised machine learning, is **a subcategory of machine learning and artificial intelligence**. It is defined by its use of labeled datasets to train algorithms that to classify data or predict outcomes accurately.

### What is supervised learning in simple words?

Supervised learning (SL) is **the machine learning task of learning a function that maps an input to an output based on example input-output pairs**. ... A supervised learning algorithm analyzes the training data and produces an inferred function, which can be used for mapping new examples.

### Is K means supervised or unsupervised?

K-means is a clustering algorithm that tries to partition a set of points into K sets (clusters) such that the points in each cluster tend to be near each other. It **is unsupervised** because the points have no external classification.
