Structural layers of ANFIS.

Layer no.	Description
1	A fuzzy layer in which every intersection is called an adaptive node. The member functions may be treated as nodal functions like the generalized bell, and Gaussian functions may be used as nodal functions
2	A product layer in which every nodal output represents the firing strength of a rule
3	A normalized layer in which each node expresses the firing strength of a rule in the normalized form
4	A defuzzy layer in which each node represents an adaptive node with a nodal function specifying the influence of the rules in terms of the overall output
5	A total output layer that describes the defuzzified output values
