Sažetak
This study deals with optimization of the clay activation process using artificial neural network models and multi-objective optimization function. Different artificial
neural network models were used for description of the relation between clay sorption capacity and the activation treatment process (power and time of clay exposure to ultrasonic
and/or microwave irradiation). Two methodologies (feed-forward and cascade-forward) in combination with five different training algorithms (random order incremental training with learning functions, resilient backpropagation, one-step secant backpropagation, Levenberg-Marquardt backpropagation, Bayesian regularization backpropagation) were applied in order to obtain an optimal artificial neural network model. The optimal
artificial neural network model showed good predictive ability (relative error 6.02 % based on external validation data set). In-house developed multi-objective criteria function
was used in combination with the developed artificial neural network model and calculated optimal activation was determined (5 minutes of ultrasoni
