Comment on “Performance of ANFIS versus MLP-NN dissolved oxygen prediction models in water quality monitoring A. Najah & A. El-Shafie & O. A. Karim & Amr H. El-Shafie. Environ Sci Pollut Res (2014) 21:1658-1670”

The title of Fig. 3 is “Optimal architecture of ANN and flowchart of algorithm procedure.” This is a detailed description of the ANFIS model (also stated by the authors at the beginning of page 1662 on the right side that the optimal ANFIS model and a flowchart of the algorithm’s procedure are illustrated in Fig. 3). The word “ANN” should be replaced by the word “ANFIS.”
