3. 3  Introduction –Artificial Intelligence (AI) –is the intelligence exhibited by machines or software, and the branch of computer science that develops machines and software with intelligence. –Machine Learning –a branch of artificial intelligence, concerns the construction and study of systems that can learn from data. Hybrid Artificial Intelligence System for Cyber Security –Pattern Recognition –in machine learning aims to classify data (patterns) based on either priori knowledge extracted from the patterns. –Classification –is the problem of identifying to which of a set of categories (sub-populations) a new observation belongs, on the basis of a training set of data containing observations (or instances) whose category membership is known (Supervised Learning).

17. 17  Evolving Computational Intelligence System for Malware Detection (ECISMD) –Evolving Classification Function (ECF) –used for pattern classification, generates rule nodes in an N dimensional input space and associate them with classes. Each rule node is defined with its centre, radius (influence field) and the class it belongs to. A learning mechanism is designed in such a way that the nodes can be generated.

19. 19  Evolving Computational Intelligence System for Malware Detection (ECISMD). Hybrid Artificial Intelligence System for Cyber Security –Genetic Algorithm for Offline ECF Optimization –A Genetic Algorithm is an evolutionary algorithm in which the principles of the Darwin's theory of evolution are applied to a population of solutions to a problem in order to "breed" better solutions. –Solutions, in this case the parameters of the ECF network, are encoded in a binary string and each solution is given a score depending on how well it performs. –Good solutions are selected more frequently for breeding, and are subjected to crossover and mutation (loosely analogous to those operations found in biological systems). –After several generations, the population of solutions should converge on a "good" solution.
