Abstract: Parallel Back-Propagation for Sales Prediction on Transputer Systems

F. M. Thiesing, U. Middelberg, O. Vornberger

In this paper artificial neural networks are adapted to a short term forecast for the sale of articles in supermarkets. The data is modelled to fit into feedforward multilayer perceptron networks that are trained by the back-propagation algorithm. For enhancement this has been parallelized in different manners. One batch and two on-line training variants are implemented on parallel Transputer-based Parsytec systems: a GCel with T805 and a GC/PP with PowerPC processors and Transputer communication links. The parallelizations run with both the runtime environments Parix and PVM.
