| Abstract: | In order to improve the global convergence speed and accuracy of forecasting,a new BP neural network based on fast bacterial foraging algorithm(FBFABP) combined with particle swarm optimization is presented.By means of the particle flying and simplifying the bacterial chemotactic action,the convergence speed and the capacity of searching global extremum of this algorithm are enhanced.Taking karst rocky desertification as example,the empirical results reveal that FBFABP some superiorities in forecasting abil... |
