Pete Warden: What Image Classifiers Can Do About Unknown Objects

Pete Warden: What Image Classifiers Can Do About Unknown Objects. “A few days ago I received a question from Plant Village, a team I’m collaborating with about a problem that’s emerged with a mobile app they’re developing. It detects plant diseases, and is delivering good results when it’s pointed at leaves, but if you point it at a computer keyboard it thinks it’s a damaged crop. This isn’t a surprising result to computer vision researchers, but it is a shock to most other people, so I want to explain why it’s happening, and what we can do about it.”
