back to article Italian researchers' silver nano-spaghetti promises to help solve power-hungry neural net problems

Researchers in Italy have developed a physical system to mimic properties of human brains that they hope will massively reduce the power costs of neural networks fundamental to AI development. Successful approaches to neural networks have largely depended on software representations of brain synapses on top of a conventional …

    Mmmmm, spaghetti ....

    </homer>

    Erm, I mean, wow, that seems interesting! Probably difficult to physically scale down, and therefore will probably fir the amount of neurones of a mouse brain in a contraption the size of a room.... but nevertheless it would still be more energy efficient than a softwrae-based neaural net, and if it's even half as clever as a mouse it would be a million times cleverer than today's neural nets

      ..a mouse brain in a contraption the size of a room...

      Oh great, house-sized robotic mice. Now you've gone and done it.

        Given that they've already mapped the nematode brain, I'd worry more about a Sand Worm sized invasion.

      I don't know about that, they are using nano wires so small that you need an electron microscope to see them. it sounds like it's already scaled down

      It's not that new

      And should be scalable, if you consider that actual human nuerons have been trained... although you would still have to feed them.

      Truly fascinating though ...

    Bistromathics!

    Bistromathics itself is simply a revolutionary new way of understanding the behavior of numbers, Just as Einstein observed that space was not an absolute but depended on the observer's movement in space and that time was not an absolute, but depended on the observer's movement in time, so it is now realized that numbers am not absolute, but depend on the observer's movement in restaurants.

    10**9 energy consumption improvement?

    That's pretty good. And combined with the neuromorphic improvement which I think will have several orders of magnitude reduction in the volume of neural nets, assuming this stuff runs at a commensurate speed, we could be getting somewhere soon!

    There's the problem

    Silver nanowires?

    Should be platinum iridium shouldn't it?

    Not a problem though, just get Powell and Donovan onto it, they'll sort it right out.

    Or Susan Calvin if you would prefer.

    Mine's the one with "I Robot" and "The rest of the robots" in the pocket.

    Neuromorphic seems very popular all of a sudden.

    Wonder where they get their inspiration? 3. 2. 1. and Turn.

      2022 would be a bit early, but putting e.g. 2030 for "Butlerian Jihad" sounds about right.

      Well, what could go wrong? I mean, we see how stable the Human brain is and what a rational mind it gives rise to . . . .

      Oh, wait . . .

    Off by a bit

    "[...] usually you have thousands of parameters that you have to train."

    No, "thousands" is for toy problems. Tens of millions is completely normal for real-world problems, with state-of-the-art nets being some orders of magnitude more complex still (GPT-3 has supposedly 175 billion).

    Perhaps the researcher was confusing the number of "parameters" with "possible combinations of hiperparameters", but that's problem-specific, so doesn't map to ANN scales directly. Either way, a bit worrying to potentially see the relevant researchers being under such a misconception – hopefully it was merely a mental hiccup.

    Regardless, progress in this problem is welcome in any case. Icon related, especially in the Summer.

    Two for the price of one?

    Seems to me they have two quite independent results here.

    One is the silver nanowire implementation of the fabled memristor. We need to know more about that technology. Can it lead to commercial memristor devices with say two terminals and predictable properties worthy of a standard spec sheet?

    T'other is that the rat's-nest, aka spaghetti, aka random, network topology has useful properties which structured topologies do not.

    Or am I missing something?

      a) yes, b) yes and c) your valiant 'or' notwithstanding, still yes.
