“…The deep belief network (DBN), the deep extreme learning machine (DELM), and the support vector machine (SVM) as three different learning algorithms were used. The second paper, authored by Jeong et al [17], attempted to develop AI suitable for solving a problem when the number of scatterers was two or three, respectively, based on convolutional neural network (CNN) models and artificial neural network (ANN) models to solve the problem of inverse scattering in some cases. To verify the performance and overfitting of the developed learning model, new limited view data that were not used for learning were created and used.…”
