Cyclone Posted December 13, 2010 Share Posted December 13, 2010 I did suggest alternatives, based on the physiology of neural networks which are not in any way binary. You don't seem to like them though, ordering to believe that your brain is like a computer. Link to comment Share on other sites More sharing options...

You don't seem to like them though, ordering to believe that your brain is like a computer. I provided wiki references to neural networks ages ago on this thread... Biological neural network The interface through which they interact with surrounding neurons usually consists of several dendrites (input connections), which are connected via synapses to other neurons, and one axon (output connection). If the sum of the input signals surpasses a certain threshold, the neuron sends an action potential (AP) at the axon hillock and transmits this electrical signal along the axon.

Biological neural network Yes, and that demonstrates that a neuron is not binary. It probably goes on to say that the output signal isn't simply on or off as well...

It probably goes on to say that the output signal isn't simply on or off as well... A single output from many inputs, so whether you speak of fuzzy logic (a threshold ) or a pure binary signal, they both do confirm binary logic...

Cyclone Posted December 14, 2010 Share Posted December 14, 2010 Binary logic works on two inputs, count 'em, two. Not multiple inputs and one varying level (ie not binary) output, but two inputs, one output which has two possible values. Neural networks are most definitely not binary.

spooky3 Posted December 14, 2010 Share Posted December 14, 2010 No, it's about the output, some binary logic gates even only have a single input! But, being no expert on the subject of biological neural networks, I even tried to encompass fuzzy logic, where I considered a threshold as binary even though it's really a form of quantisation. See here for some binary logic chips, there's loads with multiple inputs: http://en.wikipedia.org/wiki/List_of_7400_series_integrated_circuits http://en.wikipedia.org/wiki/List_of_4000_series_integrated_circuits http://www.encyclopedia.com/doc/1O11-binarylogic.html binary logic Digital logic employing two states.

spooky3 Posted December 14, 2010 Share Posted December 14, 2010 http://en.wikipedia.org/wiki/Karnaugh_map The binary digits in the map represent the function's output for any given combination of inputs. Sorry this wasn't in the previous post, I kept calling them keno tables for some reason! Link to comment Share on other sites More sharing options...
Cyclone Posted December 16, 2010 Share Posted December 16, 2010 Those multi input components are of course actually built up from single or double input sub components. Your basic binary components, NOT, OR and AND gates take 1, 2 and 2 inputs respectively and can be used to build much more complicated systems. The PC in front of me is taking input from a large number of devices right now and producing output in more than just single flashes of white on black, but it's all binary, unlike the brain.

So how does the brain work? Link to comment Share on other sites More sharing options...
