Abstract
The paper deals with Adaptive neuro-fuzzy inference system (ANFIS) and its performance. Firstly, ANFIS is described as a hybrid system based on fuzzy logic/sets and artificial neural networks. Subsequently, modifications of ANFIS are proposed. The aim of these modifications is to improve performance, accuracy or reduce computational time. Finally, experiments are presented and findings are assessed.

Notes
- 1.
Values on both axes are normalized by z-score. So they don’t directly correspond to the values of sinc.
- 2.
OrigAB is used for original ANFIS with A fuzzy sets for x and B for y while ModAB means our modified ANFIS with A fuzzy sets for x and B for y.
- 3.
Accuracy means maximal error computed using E from Eq. (20).
- 4.
Time is measured on our testing machine with Intel Core i5-2540M.
