Meet the scientists who are training AI to diagnose mental illness

Pearl Chiu has jet black hair and a bearing of quiet confidence. She pauses to think before she speaks, and radiates a teacher's joy in discussing her work. She's the only clinically trained psychologist in the lab who has direct experience with patients in a clinical setting, and she arrived at machine learning from a distinctly human place. "As I was seeing, working with, patients, I was just frustrated with how little we knew about what is happening," Chiu says. She believes bringing in machines to detect patterns may be a solution.
