“…Recently, artificial intelligence technologies such as artificial neural network ( ANN ), adaptive neuro-fuzzy inference system ( ANFIS ), and support vector machine ( SVM ) have drawn researchers’ attention because of their high capability, and flexibility in different applications including system classifications, predictive processes, and control systems [ 4 , 20 ] that can be applied to a vast range of systems to predict the behavior of experimental systems [ 21 , 22 , 23 , 24 , 25 ]. To estimate diffusivity, different types of intelligent predictive tools have been reported [ 4 , 26 , 27 , 28 , 29 ].…”
