(For more background, check out our first flowchart on "What is AI?" here.) Machine-learning algorithms use statistics ... social-media feeds like Facebook and Twitter; voice assistants like ...

Each algorithm can usually be represented by a set of straightforward steps, and programmers often use visual flowcharts to show their thought processes for solving each individual step with code.

In four new studies, researchers found complicated results from experiments on Facebook’s and Instagram’s algorithms, suggesting there was no silver bullet to fixing the platforms. By Mike ...

To clear things up, I drew you this flowchart on the back of an envelope so you can work out whether something is using AI or not. This originally appeared in our AI newsletter The Algorithm.

Can I level with you? I’m not always sure I know what people are talking about when they say algorithm? You’re not alone: Honestly, I haven’t always been sure what I meant when I said it either.
