Objective To establish Pearson correlation coefficient(PCC)and long short term memory(LSTM)neural network model for predicting the glucose content in the reaction solution during the production process of zinc gluconate.Methods Through the preparation experiment of zinc gluconate,combined with the PCC theory,the factors that have a significant impact on the glucose content of the reaction solution were determined.These factors were collected and used as input variables for the neural network.The glucose content data of the reaction solution was collected and processed as output variables of the neural network,and then a prediction model for the glucose content of the reaction solution was established using the backpropagation neural network(BP)and LSTM neural networks.Results Through 100 iterations of model training and comparing with the BP reaction solution glucose content prediction model,it could be seen that the LSTM reaction solution glucose content prediction model had an error of about 0.45%on the test set,which was relatively small and had high accuracy.Conclusion The glucose content prediction model based on LSTM reaction solution significantly improves the prediction accuracy and is more intelligent and efficient compared to existing detection methods,which can effectively assist production.
