1. Elon Musk’s OpenAI Unveils a Simpler Way for Machines to Learn

    In 2013 a British artificial-intelligence startup called DeepMind surprised computer scientists by showing off software that could learn to play classic Atari games better than an expert human player. Now OpenAI, a nonprofit research institute cofounded and funded by Elon Musk, says it has discovered an easier-to-use alternative to reinforcement learning that gets rival results when it plays games and performs other tasks. The group says it has a more practical way to get software to learn tasks, such as steering robots, that require multiple actions.
