We comment upon the very essence, roots, potentials, and applicability of computational intelligence and soft computing. We followed a different path than those traditionally employed, and which are so well and in a deep and comprehensive way documented in other papers in this special issue. First, we consider relations between computational intelligence and artificial intelligence, starting fr...

The paper presents a comparison of various soft computing techniques used for filtering and enhancing speech signals. The three major techniques that fall under soft computing are neural networks, fuzzy systems and genetic algorithms. Other hybrid techniques such as neuro-fuzzy systems are also available. In general, soft computing techniques have been experimentally observed to give far superi...

-----------------------------------------------------------------------ABSTRACT--------------------------------------------------------------We present in this paper as an introduction to soft computing techniques for fault tolerant systems and the terminology with different ways of achieving fault tolerance. The paper focuses on the problem of fault tolerance using soft computing techniques. T...
