  Artificial intelligence is fast encroaching into every area of our digital lives, picking the social media stories we see, identifying our friends and pets in photos, and even making sure we avoid accidents on the road. If you want to understand AI though, you need to start with the terms underpinning it.

And so we present to you the TechRadar glossary of AI: five of the key words and phrases you’ll want to know to get a hold on this ever-improving tech and to keep up your end of the conversation the next time the topic crops up around the dinner table. First though a disclaimer – not everyone agrees on the exact definition of some of these words, so you might see them used differently elsewhere on the web.

Wherever possible we’ve tried to stick to the most commonly used definitions, but with such a fast-growing and new technology, there are always going to be discrepancies. Ah, the famous (or infamous) algorithm.

Algorithms are sets of rules that computers can follow, so if one of your best friends posts a photo of you on Facebook, then the rules say that should go up at the top of your News Feed. Or if you need to get from A to B on Google Maps, an algorithm can help you work out the fastest route.

The rules are followed by computers but usually set by humans – so it’s the Facebook engineers who choose what makes a story important or which roads are fastest. Where AI starts to come in is in tweaking these algorithms using machine learning, so the computer begin to adapt these rules for themselves. Read more from…
