CaptionBot is Microsoft's latest AI experiment - and at least it isn't racist

After the somewhat awkward experience last month of having an AI Twitter bot go full-on racist in a few hours once it interacted with humans, Microsoft have released a new AI experiment on to the internet - CaptionBot. The idea is that you upload a photo to the service, and it tries to automatically generate a caption that describes what the algorithm sees. You are then able to rate how accurately it has detected what was on display. It learns from the rating, and in theory, the captions get better. The bot, from Microsoft's Cognitive Services team, is the result of some hefty research into how to model objects in photographs so that a computer can understand them.
