Abstract

The Ersatz Brain Project is an attempt to develop programming techniques and software applications for a brain-like computing system. Its brain-like hardware architecture design is based on a select set of ideas taken from the anatomy of mammalian neo-cortex. In common with other such attempts it is based on a massively parallel, two-dimensional array of CPUs and their associated memory. The design used in this project (1) uses an approximation to cortical computation called the network of networks which holds that the basic computing unit in the cortex is not a single neuron but groups of neurons working together in attractor networks; (2) assumes connections and data representations in cortex are sparse; (3) makes extensive use of local lateral connections and topographic data representations, and (4) scales in a natural way from small groups of neurons to the involvement of entire cortical regions.
