【Abstract】 In this paper,the comments of problems in meteorological application of neural network and its causes of formation are given.The principles and experiences of neural network structure designs and also discussed.An approach named false sample verification method is proposed to diagnose modeling problems.Finally,the principles of prediction ensemble are briefly reviewed.It is suggested that by using the method of constructing the differences among factor subsets to generate individuals for prediction ensemble,then the problems of smaller samples and factor selection may be solved.更多还原
