Computational intelligence combines elements of learning, adaptation, evolution and Fuzzy logic (rough sets) to create programs that are, in some sense, intelligent. Computational intelligence research does not reject statistical methods, but often gives a complementary view (as is the case with fuzzy systems). Artificial neural networks is a branch of computational intelligence that is closely related to machine learning.
The Computational Intelligence Society (CIS) was established in 2004 (as a name change to the Neural Network society) and is one of the fastest growing societies within the IEEE (Institute of Electrical and Electronics Engineers). Subjects in computational intelligence as defined by IEEE Computational Intelligence Society are:
