This paper presents some of the procedures adopted in the construction of a Radial Basis Function Neural Network by iteratively applying the aiNET, an Artificial Immune Systems Algorithm. These procedures have shown to be effective in terms of i) the free determination of centroids inspired by an immune heuristics; and ii) the achievement of appropriate(More)
The development of specific Decision Support Systems has been a common practice in distinct areas, such as Medicine, Engineering, and Finance. These systems has been used to help decision making in particular situations, in which the information complexity difficult an optimal human decision. The idea of this work is to propose a general auxiliary system(More)
Nematodes are vermiform animals of long and thin body and slender at the two extremities.
