Facebook last week released six videos to educate people about artificial intelligence. AI will bring major changes to society, and will be the backbone of many of the most innovative apps and services of the future, but it remains mysterious, noted Yann LeCun, Facebook’s director of AI research, and Joaquin Candela, the company’s director of applied machine learning in an online post. The videos are “simple and short introductions” that will “help everyone understand how this complex field of computer science works,” they said.
