The Application of ANN Realized by MATLAB to Underground Water Quality Assessment

The realizing function of RBF network is provided in the toolbox of MATLAB 6.5 and the method of calculating this function possesses properties such as adaptation for determining the construction network and independence of initial weight value on person. A favorable outcome appeared after we apply this function to evaluating the quality of the underground water environment in FuZhou City, attempting to use the RAND function in MATLAB to construct enough training samples, checking samples and outputs of their targets through interpolation between grades of the water quality evaluation standard, use the PREMNMX function to pretreat the original data,determine the limits of water quality grades . The methods in this paper is meaningful in improving the precision and objectivity of underground water environment quality evaluation.
