An Introduction to Supervised Learning


The term machine learning refers to a wide range of methods for extracting patterns or structures from large amounts of data. It’s often used as an umbrella term for many types of algorithms that are used in various fields, including computer science, statistics and artificial intelligence (AI). Machine learning algorithms can be used in computer programs, robots and other devices to make accurate decisions based on facts and past experience. This article provides an introduction to supervised learning – the most popular approach to machine learning – along with a summary of its advantages and limitations.

What is supervised learning?

Supervised learning is a type of machine learning, which is the process through which computers learn to make decisions based on data. In supervised learning, you give your computer lots of examples of things that have happened in the past and their outcomes (such as “this person bought this product”; “this person didn’t buy this product”). Then, you tell the computer how well each example matched up with what actually happened (“This person bought this product” vs “This person didn’t buy this product”). Based on those examples, your computer can predict what will happen next time around–or even try to understand human behavior!

Types of supervised machine learning algorithms

Supervised machine learning is used in three distinct types of problems: classification, regression and clustering.

Classification is the most common type of supervised learning. Classification algorithms are used to predict a categorical outcome (for example, “cat” or “dog”) for an input data point (for example, an image). Regression algorithms predict continuous values instead of discrete values like classification does; they’re commonly used to predict things like house prices or stock prices over time. Clustering refers to grouping data into similar groups based on their characteristics — this can be useful when you want to find patterns within your dataset that aren’t immediately obvious from looking at individual records alone

How to use supervised machine learning algorithms

Supervised machine learning algorithms are used to make predictions about the future. The first step in using a supervised machine learning algorithm is training your model, which involves feeding it data so that it can learn how to make good predictions. Once your model has been trained, you can evaluate how well it performs on new data by testing its performance against a set of labeled examples (i.e., what we want our algorithm to predict). Finally, once we’re satisfied with our model’s performance on these test sets, we can use it in production: feeding unlabeled examples into our model and letting it predict whether each one belongs or not belongs into one of two classes (e.g., spam vs non-spam emails).

Supervised learning is a popular approach to machine learning.

Supervised learning is a popular approach to machine learning. It can be used for tasks such as classification and regression, where the goal is to predict a target variable from input variables.

The basic principle behind supervised learning is that we have data with both observed values and known or desired outputs (or labels). We use this training set to train our model so that it can predict future outputs based on new observations of inputs.


In this article, we’ve explored what supervised machine learning is and how it works. We’ve also looked at the most popular algorithms for supervised learning, as well as how to use them in practice. These techniques can be applied across many industries and areas of life–from healthcare to finance or even robotics!
