To the naysayers about how possibly close we are to creating human level brains, please read the following.
The below quote indicates that -- if the bugs in the use of multi-layer memristor analog synapses integrated on top of CMOS can be worked out -- such technology may well make it possible to create neuromorphic human-level AGI’s within 5 to 15 years for 30 to100 thousand dollars, of marginal cost. This quote is from page 2 of “Training and Operation of an Integrated Neuromorphic Network Based on Metal-Oxide Memristors” by Prezioso, Merrikh-Bayat, Hoskins, Adam, Likharev, and Strukov (a 2014 paper available on the web for free): “… a CrossNets based on a hybrid CMOS/memristor circuit with 5 layers of 30-nm-pitch crossbars, 2 memristors per synapse, and 10^4 synapses per neural cell would have an areal density of ~25 million cells per cm^2, i.e. higher than that in the human cerebral cortex, at comparable average connectivity. Estimates show that at the same time, such CrossNets may provide comparable power efficiency, at a much higher operation speed – for example, an intercell signal transfer delay of ~0.02 ms (cf. ~10 ms in biology) [my comment: i.e., 500 times faster] at a readily manageable energy dissipation rate of ~1 W/cm2.” The paper goes on to state there are still multiple problems to getting such a system to work well, but claims to make significant progress toward solving one of the major such problems. So this technology is not currently a certain bet, but it is very promising. ------------------------------------------- AGI Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/21088071-f452e424 Modify Your Subscription: https://www.listbox.com/member/?member_id=21088071&id_secret=21088071-58d57657 Powered by Listbox: http://www.listbox.com
