Improved Artificial Neural Network Training Based on Response Surface Methodology for Membrane Flux Prediction
Round 1
Reviewer 1 Report
This work employed the improved artificial neural network training with response surface methodology optimization for membrane flux prediction. And the training with reduced training time and number of repetitions in achieving good model prediction for permeate flux of palm oil mill effluent. Several parameters, including the number of neurons, learning rate, momentum, epoch, and training functions, have been studied. This work is interesting and meaningful, providing a novel method to predict the membrane flux. The work is also well-organized and could be accepted in membranes.

Reviewer 2 Report
Review of membranes-1815972
This is an interesting multidiscipline manuscript about ANN (computer science) for the prediction of membrane flux (membrane science, part of chemical engineering), although based on two variables in the input layer, i.e. (1) transmembrane pressure and (2) permeate pump. However, there are a handful of issues to be clarified, as follows:
- Table 4 vs Equation 10: The significant variables from Table 4 are A, B, C, E, AE, BE. Why does Equation 10 displays A, B, C, D, E, AB, AC, AD, AE, BC, BD, BE, CD, CE, DE, AA, BB, CC, DD (and no EE)? Between Table 4 vs Equation 10, the variables must be those of significant values (p<0.05) so that the regression equation will be compact.
- Figure 6a: Please show the real number of MSECV for learning rate of 0.3 and 0.5, because those MSECV numbers are similar to the selected one (learning rate 0.7).
- Figure 7b: Please show the real number of MSECV for momentum of 0.1, 0.2, 0.3, 0.4, 0.6, and 0.7, because those MSECV numbers are similar to the selected one (momentum= 0.5).
- Figure 8c: Please show the real number of MSECV for number of epoch of 600, because those MSECV numbers are similar to the selected one (number of epoch= 1000).
