This article gives the solution and the flow chart by way of a optimization model that minimize total sum of error.According to some masters such as Trevor,it's better to take hidden cells,there is no need to use CR to achieve it.And CART is frequently used before ANN to delete some variables.With the example of ZIP code,you will see in this article that too more hidden cells may be worse than less,CR may be useful,using CART to delete some variable do little help to ANN model,along with the viewpoint that there is no paradox between the idea that from simple to general in non-complete problem and the idea that choosing all variable in complete problem.In the end,this article proposed some thought to improve.
