Implementação de redes neuronais

Abstract

The first neural networks have been simulated on sequential computers. As neural networks with some practical importance have hundreds of neurons, the simulation time has become a difficult barrier for the researchers. To avoid this problem, some researchers began to simulate on existing parallel computers. Other researchers chose to develop a specialized hardware, the NEURO-COMPUTERS, that can be eletronic or eletro-optic. The eletronic implementation can use commercial or special chips, the NEURAL-CHIPS, and have digital or analog implementation. The eletro-optic implementation is called OPTICAL NEURAL-COMPUTERS. This work discribes four implementations for neural networks: analog neural-computer, digital neural-computer, optical neural-computer, and simulation on a parallel computer.
