A New Direction for Artificial Intelligence?
OpenAI will describe a new machine-learning approach at MIT Technology Review’s EmTech Digital conference.
Ilya Sutskever, director of OpenAI, an independent research group, will describe what might be the next big breakthrough in artificial intelligence today at EmTech Digital, a conference organized by MIT Technology Review in San Francisco.
Sutskever will describe research showing an approach in machine learning that can perform even better than methods that have produced huge breakthroughs recently. His technique may also prove far more scalable.
In a blog post describing the work, Sutskever and colleagues describe using “evolutionary strategies” to have machines figure out for themselves how to solve a complex task. The researchers say the approach is distantly related to a decades-old approach that involves optimizing algorithms using a process of simulated evolution. It essentially lets a machine work out, using experimentation and optimization, the best algorithm for solving a complex problem, and it could have applications in robotics, automated driving, and other areas.
The OpenAI researchers compare their evolutionary strategies approach to reinforcement learning, a technique that has produced some impressive results in the past year or so, including enabling a computer to defeat one of the world’s best Go players (see “10 Breakthrough Technologies: Reinforcement Learning”). Reinforcement learning, which is loosely based on the way animals seem to learn through experience, enables machines to figure out how to do things that are difficult or impossible for a person to describe in code.
Unlike reinforcement learning, evolutionary strategies allow machines to learn while using much less computation. Reinforcement learning typically requires a technique known as backpropagation, which optimizes a neural network as errors are minimized. Evolutionary strategies involve a much simpler optimization technique.
