In this paper, an immune-inspired model, named innate and adaptive artificial immune system (IA-AIS) is proposed and applied to the problem of identification of unsolicited bulk e-mail messages (SPAM). It integrates entities analogous to macrophages, B and T lymphocytes, modeling both the innate and the adaptive immune systems. An implementation of the(More)
This paper presents the computer aided simulation of a model for the control of an immune response. This model has been developed to investigate the proposed hypothesis that the same cytokine that amplifies an initiated response can eventually lead to its downregulation, if it can act on more than one cell type. The simulation environment is composed of(More)
Rough Set Theory (RST) is a mathematical formalism for representing uncertainty that can be considered an extension of the classical set theory. It has been used in many different research areas, including those related to inductive machine learning and reduction of knowledge in knowledge-based systems. One important concept related to RST is that of a(More)
