Includes bibliographical references. "We discuss some preliminary results of a neural network approach to predict missing environmental data. One of the main problems in environmental modelling and expert system application is the lack of useful data. The neural network approach will no doubt provide more useful data. It is found that the neural network, when used with proper pre-screening processes, produces satisfactory results. The preprocessing techniques used here are the cluster analysis to filter noisy data and the transformation to align the data in the appropriate range. Design procedures for this application are given and its performance is discussed by means of a sensitivity analysis"--Abstract. gccst Environmental sciences gccst Information systems gccst Intelligent systems Lam, D.
