Andrew Ng: Unbiggen AI

Andrew Ng has serious street cred in artificial intelligence. He pioneered the use of graphics processing units (GPUs) to train deep learning models in the late 2000s with his students at Stanford University, cofounded Google Brain in 2011, and then served for three years as chief scientist for Baidu, where he helped build the Chinese tech giant's AI group. So when he says he has identified the next big shift in artificial intelligence, people listen. And that's what he told IEEE Spectrum in an exclusive Q&A. Ng's current efforts are focused on his company Landing AI, which built a platform called LandingLens to help manufacturers improve visual inspection with computer vision. He has also become something of an evangelist for what he calls the data-centric AI movement, which he says can yield "small data" solutions to big issues in AI, including model efficiency, accuracy, and bias.
