We should let go of this idea that artificial neural networks have
anything to do with the brain. ANNs are just a family of parametric
functions (often with too many parameters for their own good) and
associated tuning algorithms ("learning" is a bit pretentious).
Perhaps they took vague inspiration in a cartoonish version of the
brain, but that's about it.People tried to make flying machines by imitating birds for a long time. Planes and helicopters fly, but not like birds do it. Similarly, I believe that whenever we figure out how to make machines that play go well, they will not do it like a brain does it. Álvaro.
