Probability-based processors-Bayesian NAND gates

This article is very interesting....but a bit hard to get your
head around. It's just so bizarre...... a silicon chip that computes
with electrical signals that represent chances, not digital 1s and 0s.
It seems like something you could do in software, although
not as fast as a processor dedicated to the task.

    Interesting Holly, used in future pc's? ---probably :)

    Computers that say "maybe"; wow! One day in the future, our digital 1's and 0's will seem crude and laughable, like the Roman Emperor giving a thumbs up or down.

    But for now, give me digital or give me death!

    I don't know that the galdiators thought it was laughable...

    Touche, John. But those poor lions & tigers had to get fed one way or the other. Real cat lovers (nice avatar!) must have mixed emotions!

    Not at all. I'm completely on the side of the lions and tigers.

    This morning I watched one of the neighborhood strays take a mouse from the neighbor's garden as the sun rose: a thing of beauty.

    Interesting article. So basically this processor will look at raw data, and based upon previous data, generate the most probable output? But, what would happen if the most probable event was not the one that occurred? You are right Holly. It is a very hard concept to wrap your noggin around and then there is talk of "quantum computers" and "race track memory" and "memristors". I hope normal digital computers will be around for a little longer, haha.

    It would be interesting to see if these chips could be used to construct functioning neural nets.

    You can ask the chip and it will tell you "Probably!" But if we implemented that same logic in a prop, it would tell you "Propably!"
