Giving purpose to AI: Deep reinforcement learning

The field of artificial intelligence has grown by leaps and bounds in recent years, already providing new capabilities that we see used in real life. Smart phones can recognize our faces to identify us as their proper owners. We can now translate street signs in a different language using an app. And we are starting to have computers that can respond to voice commands. The future seems bright, with talk of autonomous vehicles, robots, and advances in many different fields--from medical diagnostics to automated factories.
