Towards Computational Models of the Brain:
Getting Started
Abstract
We present an overview of known results from machine oriented complexity
theory which relate to brain-like computing. First, a brief survey of
complexity results on various kinds of finite neural networks is given.
The lower bound on their computational and descriptive power is obtained
with the help of so called neuromata. Then, subsequently, three
computational models of the brain are presented: Valiant's neuroidal
tabula rasa, the memory surface model by Goldschlager, and
de Bruijn's model of a brain as a molecular computer. These three
models are compared and their weaknesses as well as advantages are
discussed. Finally, the prospects of computer simulation of the above
models of brain are investigated.
Tervetuloa!
