What is unsupervised machine learning?

Artificial intelligence (AI) is a field focused on enabling machines and software to process information and make decisions autonomously. A component of AI, machine learning includes computer systems that enhance problem solving and understanding of complex problems through automation techniques.

The three core machine learning methodologies available to programmers are supervised learning, unsupervised learning, and reinforcement learning. For more information on supervised machine learning and reinforcement machine learning, see our dedicated articles. You can read about the basics of unsupervised machine learning here.

Systems that use unsupervised machine learning are like curious toddlers exploring a world they know nothing about. The system explores the data without knowing what it is looking for, but when it encounters new patterns it gets excited in a digital way.

In this type of machine learning, algorithms sift through large amounts of unstructured data with no particular direction or end goal in mind. They look for previously unknown patterns in the same way that they look for new stocks in the overlooked corners of the market. Raw data owners typically apply more advanced deep learning or supervised machine learning analysis to potentially interesting patterns, so this is rarely the last step.

Why should I care about this artificially intelligent infant exploring without a clear goal? In fact, unsupervised machine learning is at the cutting edge of technology and innovation. It plays a vital role in everything from self-driving cars learning how to navigate the roads to recommendation algorithms in your favorite streaming platform. This pattern-discovery method is a powerful first step in detailed analysis of any complex topic, from weather forecasts to genetic research.

The two main types of unsupervised learning are clustering and association.

• Clustering is like categorizing a random pile of stocks into sectors with common themes or qualities. It’s all about grouping similar things together.
• The Association, on the other hand, is like recognizing that smartphone component stock prices often go up when: apple (AAPL 1.56%) announced the new iPhone. It’s about finding relationships and connections between seemingly separate things.

Now you know what unsupervised machine learning is and why it matters. How can you take this newfound knowledge and put it to good use?

First and foremost, you can make informed investment decisions. Companies that leverage unsupervised learning are often poised to grow as this technology continues to evolve.think about Amazon (AMZN 2.54%) using unsupervised learning for product recommendations, or Netflix (NFLX 0.94%) runs unsupervised machine learning routines over years of collected audience data to generate streaming homepages and make future content production decisions.

These applications are not just fun toys, they are engines of business advantage and growth.

And AI and machine learning continue to reshape many industries. Whether you’re interested in FAANG stocks or emerging AI startups, your knowledge of unsupervised learning will give you an advantage when assessing a company’s technological prowess and potential for future success.

Unsupervised Learning in Practice: Connecting Social Media

We all appreciate a little connection, right? Thanks to unsupervised machine learning, we’re getting better at finding people we know and like on social media platforms. Facebook is a prime example.

Ever wonder how Facebook knows who your real high school friends are—the ones you actually want to keep in touch with? It’s not magic. It’s real unsupervised learning.

meta platform‘ (meta 2.3%) Large social networks continuously analyze large amounts of user data, looking for patterns and traits shared among users. Mutual friends can be helpful clues. Similar locations and common interests may steer platforms in the right direction, and mutual workplaces may be the determining factor. None of these traits are sufficient to find a long-lost lover or forgotten friend, but they are enhanced by the power of unsupervised machine learning algorithms.

So when Facebook suggests “people you might know”, you basically get the output of an unsupervised learning model. Social networks aren’t just pulling these suggestions out of their digital hats. Each is the result of a complex analysis of patterns and connections.
