“…The artificial neural network method (ANN) has been used to solve several problems in different fields; it is a logic programming technique developed that is based on learning from experimental or analytical/theoretical data available to solve complex problems [ 23 , 24 , 25 , 26 ], which maps the input parameters to a specific output, and the formal neuron or perceptron mimics the functioning of a biological neuron to perform functions such as learning, memorization and decision, which is the basis of an ANN method. In this study, we calculated the bandgap energy of GaAN using an ANN and we conducted a comparative study between the experimental results, the results obtained by the ANN method, and the conduction band anticrossing model (CBAC) to test the robustness of the ANN method.…”
