Neural network prediction model and high-risk warning range of NRS. (A) The neural network prediction model reached the best effect, in which the mean squared error was 0.0076566 at epoch 2000. (B) The final training model of the neural network prediction model, and the relativity is 0.98987. (C) Verify the predicted value of the data against the actual value. (D) Verify the data error percentage curve. (E) The high-risk warning range of NRS at the level of the planform. (F) The high-risk warning range of NRS at the level of the three-dimensional stereogram.
