The idea is that neuro chips are error tolerant and such can deal with manufacture tolerances better. As we shrink silicon more perhaps we will abandon fragile digital design and go for self organising neuro inspired design.
I am somewhat skeptical as we don't do that kind of computimg in software. I can't yet imagine doing a whole application using 90% neural nets.
- neolefty 13y agoRather than "fragile digital" it may be more apropos to say "efficient analog". If anything, analog is more fragile -- affected by changes in temperature, drive voltage, chemical gradients across individual chips. Digital is an escape from that fragility, but at the expense of power efficiency and speed.
- tlarkworthy 13y agoI think of digital as a logical house of cards. A single flip of a bit has a cascade of effects. Analogue is affected by lots of things, but good analogue design is robust to these perturbations. Digital circuits can't be perturbed outside their tolerances. Digital design can't generally deal with a noisy AND. It this kind of manufacturing noise they want to deal with with neuromorphic chips. As I said, I am sceptical myself but that's the justification I have heard from this research domain.
