【Abstract】 After analyzing the conventional artificial neural network prediction model,we propose to modify the weight with Simulated Annealing instead of local gradient descend.Thereby, prevent the artifical neural network from resulting in local minimum. This method is able to efficiently improve the prediction accuracy by case.更多还原
