The Future of Deep Learning Is Unsupervised, AI Pioneers Say

NEW YORK--Machines can do well at recognizing images and understanding language--when humans are involved with training. But for AI to reach new heights, the technology must figure out how to learn on its own, according to three AI pioneers who spoke Sunday at a technology conference. Yann LeCun, chief AI scientist at Facebook Inc., said neural networks power AI systems that can do everything from detecting tumors to pointing out malicious content on social media. For the most part, those systems undergo supervised learning,...
