%X A new predict model was contrived,which involves local stream energy prediction,the energy distribution pattern mining,the predictive series reconstruction and measurement method of stream energy.A new method was designed to forecast stream by energy regression and wavelets decomposing based on frequent pattern, and extended to multi-streams with strong coincidence.The concept of the nearest maximum frequent pattern was proposed to decompose local stream energy.The validity of new algorithm was demonstrated by extensive experiments on real data.
