My Fitbit sends me encouraging notes throughout the day. My iPhone does a remarkable job of telling me where I am, where I should be, and how to get from here to there. And then there’s my Honda, reminding me what music I last listened to. Would I like to hear something else?

For the most part, these devices work well, and I am pleased with the convenience that all this robust connectivity offers. On a more global scale, when my personal data is added to that of millions of others, I see the enormous value in all that aggregated information, culled and parsed by ever larger and more interconnected networks.

Think of the many tasks to which computers are being applied that in the not-so-distant past required human intuition. Computers routinely identify objects in images, transcribe speech, translate between languages, diagnose medical conditions, play complex games, and drive cars.

The technique that has empowered these stunning developments is called deep learning, a term that refers to mathematical models known as artificial neural networks. Deep learning is a subfield of machine learning, a branch of computer science based on fitting complex models to data.
