My copy arrived today and it seems like a interesting piece of work. >From Chris Eliasmith book “How to build a BRAIN a neural architecture for >biological cognition” preface (XII):
“The architecture I propose and develop in this book is called the “Semantic Pointer Architecture" (SPA), for reasons that will subsequently become clear. I believe a central departure of the SPA from past attempts to articulate theories of cognition is that cognitive systems perform logic-like computations in a language of thought or that they are best described as abstract nodes connected together in a network. Rather, it gives equal time to Biology.” -Hannu On 01 Nov 2013, at 01:40, Azat <[email protected]> wrote: > http://www.amazon.com/How-Build-Brain-Architecture-Architectures/dp/0199794545/ref=sr_1_1?s=books&ie=UTF8&qid=1383266328&sr=1-1 > > Azat > > -------------------------------------------- > On Thu, 10/31/13, Dean Horak <[email protected]> wrote: > > Subject: [nupic-dev] Using NuPIC as an engine for WBE > To: [email protected] > Date: Thursday, October 31, 2013, 6:28 PM > > I'm in the beginning stages of > planning a project to perform whole brain emulation and am > considering using NuPIC as the engine.
