hit it can't predict anything when the first image first flash is on so you get a big bunch of activity but then as it locks on and learns to sort of explain away the data then it goes down and then when you get the image off that's another sort of surprise and then you get another burst of activity yeah if you sprinkled the pixels randomly like you know Toby Delbert's event cameras or something true continue so so it's true we're doing this in discrete time because we're talking about worker L STM's and things like that
