To a large extent Computational intelligence has been found to be efective in designing such models. Bio inspired computing is the technique which makes the machines intelligent by adapting the behavior and methods exhibited by the human beings and other living organisms while forming intelligent systems. These intelligent models include the intelligent techniques such as Artifcial Neural Network (ANN), evolutionary computation, swarm intelligence, fuzzy system, artifcial immune system accompanied by fuzzy logic, expert system, deductive reasoning. All these together form the area of Bio inspired com- puting. The chapter deals with various bio inspired technique, giving emphasis on issues, development, advances and practical implementations of ANN. INTRODUCTION Bio inspired computing (also biologically inspired computing or bio computing) is a field of computing that deals with the subfields related to the topics of connectionism, social behavior, and emergence. It closely related to the field of artificial intelligence, as many of its pursuits can be linked to machine learn- ing. It relies heavily on the fields of biology, computer science, and mathematics. Biologically inspired computing is an important subset of natural computation. The concept of bio computing has a twofold definition: the use of biology or biological processes as metaphor, inspiration, or enabler in developing new computing technologies and new areas of computer science; and conversely, the use of information Bio-Inspired Computing through Artifcial Neural Network Nilamadhab Dash C.
