ABSTRACT
In this highly incorporated era, people need a tool that can be applicable to the problems arising in different fields. In this sense soft computing is an emerging computing approach for upcoming years. Soft computing gives the flexibility to model the problem according to given constraints. It helps to find quick solutions to the problems arising in various disciplines. Life is full of uncertainties; it can be vague or imprecise. To deal with such uncertainties probability theory used to be a tool for mathematicians, which is based on classical set theory. A function that describes the membership grades of elements in a fuzzy set is said to be a membership function. A neural network is a complex network of neurons. Neurons are responsible for processing and storing the information. One of the main concepts of artificial neural network is the firing rule. A firing rule decides whether the neuron will get activated or not with any input pattern.
