Error analysis & correction of BP network

Artificial Neural Networks is an information processing system that imitates the human brain structure and its func- tions.In dealing with non-linear issue,this method demonstrates its unique advantages,and more and more people are concerned a- bout it in engineering applications area.At the same time,the accuracy and convergence speed in Neural Networks computing have al- so been becoming a common concern.It is found that BP Neural Network Algorithm exists Max Error and Space Deformation Error in the application process.In order to control these Errors,the conventional BP Network Algorithms is improved and has enhanced its the forecast accuracy in this paper.
