Introduction to ANN (Artificial Neural Networks) | Set 3 (Hybrid Systems)
New Password. Therein neural networks have an advantage over expert systems, and they can manage with far less information than expert systems need. One form of fuzziness in neural networks is called a fuzzy cognitive map. A fuzzy cognitive map is like a dynamic state machine with fuzzy states. A traditional state machine is a machine with defined states and outputs associated with each state. Transitions from state to state take place according to input events or stimuli. A fuzzy cognitive map looks like a state machine but has fuzzy states not just 1 or 0. You have a set of weights along each transition path, and these weights can be learned from a set of training data.
Our treatment of fuzziness in neural networks is with the discussion of the fuzzy associative memory, abbreviated as FAM , which, like the fuzzy cognitive map, was developed by Bart Kosko.
So far we have considered how fuzzy logic plays a role in neural networks. The converse relationship, neural networks in fuzzy systems, is also an active area of research.
Neural network and fuzzy logic applications in C/C++ ( edition) | Open Library
In order to build a fuzzy system, you must have a set of membership rules for fuzzy categories. It is sometimes difficult to deduce these membership rules with a given set of complex data. Why not use a neural network to define the fuzzy rules for you? A neural network is good at discovering relationships and patterns in data and can be used to preprocess data in a fuzzy system.

Further, a neural network that can learn new relationships with new input data can be used to refine fuzzy rules to create a fuzzy adaptive system. Neural trained fuzzy systems are being used in many commercial applications, especially in Japan:. In this chapter, you read about fuzzy logic, fuzzy sets, and simple operations on fuzzy sets.
Fuzzy logic, unlike Boolean logic, has more than two on or off categories to describe behavior of systems. You use membership values for data in fuzzy categories, which may overlap. For use with neural networks, fuzzy logic can serve as a post-processing or pre-processing filter. Kosko developed neural networks that use fuzziness and called them fuzzy associative memories , which will be discussed in later chapters. You also read about how neural networks can be used in fuzzy systems to define membership functions and fuzzy rules.
