In this paper we discuss on the necessity of applying data mining operators on information systems containing a set of variables which describe the characteristics and behaviors of a specific system and could be exploited in approximating system°¶s functionality. For the problem of function approximation, we developed a new approach combining two intelligent methods. At first we used an algorithm based on the notions of rough set theory as a preprocessor to our information system. Afterward an artificial neural network is employed as a function approximator to obtain values for decision attributes of information system while values of condition ones are passed to the network. This method has been applied to a real problem of approximating values for two hydraulic- geotechnical control variables of rubble mound breakwaters, and the results have been discussed.

Keywords: data mining, information systems, modeling, function approximation, rough sets theory, artificial neural networks
