AI Can Now Understand Your Videos by Watching Them

A new artificial intelligence system (AI) could watch and listen to your videos and label things that are happening. MIT researchers have developed a technique that teaches AI to capture actions shared between video and audio. For example, their method can understand that the act of a baby crying in a video is related to the spoken word "crying" in a sound clip. It's part of an effort to teach AI how to understand concepts that humans have no trouble learning, but that computers find hard to grasp. "The prevalent learning paradigm, supervised learning, works well when you have datasets that are well described and complete," AI expert Phil Winder told Lifewire in an email interview.
