www.csetube.in Introduction Basics of Soft Computing What is Soft Computing ? • The idea of soft computing was initiated in 1981 when Lotfi A. Zadeh published his first paper on soft data analysis “What is Soft Computing”, Soft Computing. Springer-Verlag Germany/USA 1997.]. • Zadeh, defined Soft Computing into one multidisciplinary system as the fusion of the fields of Fuzzy Logic, Neuro-Computing, Evolutionary and Genetic Computing, and Probabilistic Computing. in • Soft Computing is the fusion of methodologies designed to model and difficult to model mathematically. e. enable solutions to real world problems, which are not modeled or too ub • The aim of Soft Computing is to exploit the tolerance for imprecision, in order to achieve et uncertainty, approximate reasoning, and partial truth cs close resemblance with human like decision making. = ww SC Soft Computing Zadeh 1981 EC w. • The Soft Computing – development history = EC + NN + FL Evolutionary Computing Neural Network Fuzzy Logic Rechenberg 1960 McCulloch 1943 Zadeh 1965 GP + ES + EP + GA Evolutionary Computing Genetic Programming Evolution Strategies Evolutionary Programming Genetic Algorithms Rechenberg 1960 Koza 1992 Rechenberg 1965 Fogel 1962 Holland 1970 03 www.csetube.in

www.csetube.in SC - Definitions 1. Introduction To begin, first explained, the definitions, the goals, and the importance of the soft computing. Later, presented its different fields, that is, Fuzzy Computing, Neural Computing, Genetic Algorithms, and more. Definitions of Soft Computing (SC) Lotfi A. Zadeh, 1992 : “Soft Computing is an emerging approach to computing which parallel the remarkable ability of the human mind to reason and learn in a environment of uncertainty and imprecision”. The Soft Computing consists of several computing paradigms mainly : Fuzzy Systems, Neural Networks, and Genetic Algorithms. in • Fuzzy set : for knowledge representation via fuzzy If – Then rules. e. • Neural Networks : for learning and adaptation ub • Genetic Algorithms : for evolutionary computation et These methodologies form the core of SC. cs Hybridization of these three creates a successful synergic effect; that is, hybridization creates a situation where different entities cooperate ww w. advantageously for a final outcome. Soft Computing is still growing and developing. Hence, a clear definite agreement on what comprises Soft Computing has not yet been reached. More new sciences are still merging into Soft Computing. 04 www.csetube.in
