A multilayer-perceptron network is usedfor training. The results indicate that the Bayesian regularization method with four neurons in the hidden layer with a tansig activation function and one neuron in the output layer with a purelin function gives the best results. It is found that the errors for the predicted data of the lattice parameters of a and c are less than 1 % and 2 %, respectively. On the other hand, about 3 % errors were encountered for both lattice parameters of the non-stoichiometric apatites with exact formulas in the presence of the T-site ions that are not used for training the artificial neural network"},{"@xml:lang":"sl","#text":"V tej študiji so z uporabo umetnih nevronskih mrež napovedani heksagonalni mrežni parametri (a in c) in prostornina osnovne celice nestehiometričnega apatita M10(TO4)6X2 iz njihovih ionskih premerov.
