In order to accurately predict mine gas flow volume, based on the theory of the gray model, analyses the GM(1,1) mechanism, and point out the model of theoretical defects, than do optimum to the model of time response function. Optimum model will use to mine gas flow volume of prediction, the prediction accuracy for 98.1784%. Results show that the optimum model for the mine gas flow volume prediction...
Recently, support vector machines is a focus research field in the world, support vector regression which is used as a technology to solve the regression problems have the advantages of global optimal solutions, the solutions avoiding overtraining and so on. This paper establishes a model of exchange rate prediction based on support vector machines, collects the daily data of USD/GBP exchange rate...
