Google's AI is getting really good at captioning photos

It's great to be an AI developer right now, but maybe not a good time to have a job that can be done by a machine. Take image captioning -- Google has released its "Show and Tell" algorithm to developers, who can train it recognize objects in photos with up to 93.9 percent accuracy. That's a significant improvement from just two years ago, when it could correctly classify 89.6 percent of images. Better photo descriptions can be used in numerous ways to help historians, visually impaired folks, and of course, other AI researchers, to name a few examples. Google's open-source code release uses its third-gen "Inception" model and a new vision system that's better at picking out individual objects in a shot.
