Statistical optimization of the phytoremediation of arsenic by Ludwigia octovalvis- in a pilot reed bed using response surface methodology (RSM) versus an artificial neural network (ANN)

Abstract: In this study, the removal of arsenic (As) by plant, Ludwigia octovalvis, in a pilot reed bed was optimized. A Box-Behnken design was employed including a comparative analysis of both Response Surface Methodology (RSM) and an Artificial Neural Network (ANN) for the prediction of maximum arsenic removal. The predicted optimum condition using the desirability function of both models was 39 mg kg for the arsenic concentration in soil, an elapsed time of 42 days (the sampling day) and an aeration rate of 0.22 L/mi… Show more

“…The interaction effect of temperature and substrate concentration on sugar yield was represented in Figure 6 calculated by ANN. In most of the cases in optimization of bioprocesses ANN performed better than the RSM (Zafar et al, 2012;Nelofer et al, 2012;Siddique et al, 2014;Titah et al, 2018). In the present studies ANN gave the prediction of optimal levels close to the actual with 85.5% saccharification of wheat straw.…”

“…The topology of the ANN was based on the number of hidden neurons chosen. The optimum number of hidden neurons was selected by trial‐and‐error procedure, the software autosearching for the best network by varying number of hidden neurons, and the nodes (neurons) within each layer (Titah et al, ). Different numbers of neurons were tested iteratively by adjusting the strength of connections between neurons with the aim to adapt the output of the entire network to be closer to the desired outputs or until minimum value of sum of squares error was identified.…”
