“…The map usually has a 2D structure with a map unit associated with a weight vector. where N ij is a 2D map grid (also called a neuron); W ij is the weight vector assigned to (i, j), the unit of SOM architecture; and L and M are number of rows and columns, respectively 43 45 . The steps of the SOM algorithm are displayed as follows: Step 1: Data normalization and SOM network initialize, the weight vector w ij ( i = 1 , 2 , …… , S; j = 1, 2, 3, ……, R ) is randomly set in the interval [0, 1], R is the sample dimension, and S is the number of output neurons.…”

“…Inside the black-box, a network is formed within the neurons which is similar to that of the nervous system in human brain [23,24,28]. The advantages of the ANN models include: (i) generalization of the unseen situations [29,30], (ii) ability to perform model-free function estimations, (iii) ability to learn from data relationships that are not otherwise known and, (iv) ability of handling non-linear functions [31,32]. The ANN model consists of input layer, hidden layer and output layer [33].…”

“…Candelieri [16] used clustering algorithms to detect water consumption patterns before applying short-term forecasting models. Similarly, Farzad and El-Shafie [17] enhanced the typical ANNs rainfall-water level data prediction model with the SOM clustering method in an unsupervised manner. Kardan Moghaddam et al [18] instead used spatial clustering approaches in a combination with machine learning models to predict aquifer groundwater level.…”
