Prediction of Grain Yield in Henan Province Based on Grey BP Neural Network Model
BP neural network (BPNN) is widely used due to its good generalization and robustness, but the model has the defect that it cannot automatically optimize the input variables. In response to this problem, this study uses the grey relational analysis method to rank the importance of input variables, o...
