I think it's another stream of data feeding the model. For example: you see a child walking along close to the edge of the road, not looking in your direction.

I think it's another stream of data feeding the model. For example: you see a child walking along close to the edge of the road, not looking in your direction. You don't slam your brakes on, but as a driver your prediction is that he may step in front of you, so you ease back on the accelerator, move out further into the middle of the road, cover the brake.
