Neural net predictions
I'm not well up on neural networks or machine learning, but from what I've read here and elsewhere, nobody really understands how they work. I can sort of understand how you can train a neural net to recognise various features in images, because you can test that. But I don't understand how you can use one to make predictions in this way - how do you verify the results?
Can we have an icon for "thinking about this makes my head hurt"?
