Alan Turings unorganized machines and artificial neural networks: his remarkable early work and future possibilities
In a technical report submitted in 1948, Alan Turing presented a far-sighted survey of the prospect of constructing machines capable of intelligent behaviour. This report was all the more remarkable for having been written at a time when the first programmable digital computers were just beginning to be built, leaving Turing with only paper and pencil with which to explore his modern computational ideas. Turing may have been the first to suggest using randomly connected networks of neuron-like nodes to perform computation, and proposed the construction of large, brain-like networks of such neurons capable of being trained as one would teach a child. Some modern work has been performed on Turings neural networks, but all of it involves the invention of new structures outside the scope of Turings original specifications in order to solve a technical error on Turings part. I propose an alternative solution to Turings technical error, one which does not require the invention of new structures, and outline an approach which may allow the better exploration of the particular properties of Turings networks in their own right. I also give examples of ways in which to avoid viewing Turings early and strikingly original work through the lens of the conventions of modern neural network theory. Using a genetical search to configure such networks, as Turing suggested, is likely to yield non-intuitive or algorithmically opaque results, but this is likely to be a property of brain-like networks themselves, and a sign we are approaching Turings initial goal.
