The forecast exchange rate has become more and more attention, especially because of the important financial issues, inherent difficulties and practical applications; many attempts to improve the nonlinear model to obtain accurate predictions. Performance-based mining ID3 maximum number of dimensions of the multi-element method close. Among them, the neural network model is based on data mining to encourage results. This gift is one step of their performance. Several methods, radiation-based function, dynamic neural networks and fuzzy systems, discussion and recommendations, including a multi-element dimensions progeny. It improves neural networks and fuzzy models used to predict the exchange rate and a multi-step ahead forecast. Throughout the investigation process, it will be evaluated using the actual value per day of the exchange rate and the British pound in U.S. dollars.
