Research and application of a neural network classifier based on dynamic threshold

In this study,a Multi-Layer BP neural network (MLBP) with dynamic thresholds is employed to build a classifier model.As to the design of the neural network structure,theoretical guidance and plentiful experiments are combined to optimize the hidden layers'parameters which include the number of hidden layers and their node numbers.The classifier with dynamic thresholds is used to standardize the output for the first time.and it improves the robustness of the model to a high level.Finally,the classifier is applied to forecast box office revenue of a movie before its theatrical release.The comparison results with the MLP method show that the MLBP classifier model achieves more satisfactory results,and it is more reliable and effective to solve the problem.
