Personally I know of no software that can currently reverse a jpeg into raw.
Print at high res, then take a picture of the print!
I'm still mystified by the desire to make computational neural nets more like biological ones. Biological neurons are *bad* in many ways -- for one, they are composed of a large number of high signal-to-noise sensors (ion channels). This random behavior is necessary to conserve energy and space in a brain. But computers have random-access memory and energy isn't really a limiting factor; why impose these flaws?
Sure, there may be things that can be discovered by playing with network models more inspired by biology. But there's this bizarre meme going around that we have to make computers act like brains for them to be any good. We don't.
I saw a man wearing a plain gray shirt, denim jeans, a hard hat, and a well stocked tool pouch walking my way towards the relay box with a large pair of bolt cutters slung over his shoulder.
