A HARDWARE IMPLEMENTATION OF A NEURAL-NETWORK USING THE PARALLEL PROPAGATED TARGETS ALGORITHM

This document describes a proposal for the implementation of a new VLSI neural network technique called Parallel Propagated Targets (PPT). This technique differs from existing techniques because all layers, within a given network, can learn simultaneously and not sequentially as with the Back Propagation algorithm. The Parallel Propagated Target algorithm uses only information local to each layer and therefore there is no backward flow of information within the network. This allows a simplification in the system design and a reduction in the complexity of implementation, as well as acheiving greater efficiency in terms of computation. Since all synapses can be calculated simultaneously it is possible using the PPT neural algorithm, to parallelly compute all layers of a multi-layered network for the first time.
