چکیده مقاله :
This study focuses on the estimation of the mean grain size of mechanically induced Hydroxyapatite (HA) through the artificial neural network (ANN) model. The mean grain size of HA and HA based nanocomposites at different milling parameters were obtained from previous studies. The data were trained and tested by the neural network modeling. Accordingly, all data (55 sets) were based on the mechanically alloying process and were randomly divided into 40 sets for training and 15 sets for testing data, respectively. The data used in the multilayer feed forward neural networks models and input variables of models were arranged in a format of 13 input parameters. The results indicated a very good agreement between the experimental data and the predicted ones. R2 value of the trained and tested suggested model confirmed this situation. Given the broad range of the parameters used, it was found that our analysis and model were fully functional to accurately estimate the optimal conditions for experiments. This shows the potential application of these calculations and analysis in a wide range of numerical studies.
