PsythikI hate those the most. I get it wrong every single time. Well excuse me for including the rider as part of the motorcycle. I’m trying to save them from self-driving cars clipping their arm or leg on public roads.
How would they even know when they’re using it train bots?
The same image is shown to a lot of people. If a majority of people click on the same things, that is assumed to be the correct answer. And it is added to the training database. Occasionally you’ll get one that hasn’t been shown to enough people yet to know for sure. For those, they’ll usually accept any answer, even wildly incorrect ones. The thing is, you as a user never know which ones they already know and which they don’t.
