From Self-Flying Helicopters to Classrooms of the Future

Jeffrey Young:

n a summer day four years ago, a Stanford University computer-science professor named Andrew Ng held an unusual air show on a field near the campus. His fleet of small helicopter drones flew under computer control, piloted by artificial-intelligence software that could teach itself to fly after watching a human operator. By the end of the day, the copters were hot-dogging--flipping, rolling, even hovering upside down.

It was a milestone for the field of "machine learning," the same area of artificial intelligence that lets Amazon recommend books based on a shopper's previous habits and helps Google tailor search results to a user's behavior. Mr. Ng and his team of graduate students showed that artificial-intelligence software could control one of the hardest-to-maneuver vehicles and keep it stable while flying at 45 miles an hour. That same year, Technology Review, published by the Massachusetts Institute of Technology, included Mr. Ng among the top 35 innovators in the world under the age of 35.

Today Mr. Ng is an innovator in an entirely different setting: online education. He is a founder of the start-up Coursera, which works with 33 colleges to help them deliver free online courses. After less than a year of operation, the company already claims more students--1.3 million--than just about any educational institution on the planet. Mr. Ng likes to say that Coursera arrived at an "inflection point" for the idea of massive open online courses, or MOOC's, which are designed so a single professor can teach tens of thousands of students at a time.
