Application of 3-layer perceptrons to cost estimation

Description

This item was taken from the IEEE Periodical ' Application of 3-layer perceptrons to cost estimation ' During planning and designing of new products the design managers are interested in estimating the cost as early as possible. However, at the early design stage only a few attributes of the future product are known, and their impact on cost is not clear to the cost estimation expert. Neural networks can be used to detect the hidden relationships between cost drivers and the cost of a new product, and estimate the cost after being presented a small set of conceptual attributes describing the product. Based on a laboratory benchmark example with artificial data we present our experiments on classification perceptrons with one hidden layer. The attention is focused on the problem of small number of training samples available in the domain. The results of three possible remedies are presented namely: prewiring background knowledge, preprocessing input data, and transforming input data.
