“…[17] It has received great attention and wide applications in material sciences, [18][19][20][21] condensed matter physics, [22,23] etc. [24,25] The unique qualities of SVR include non-convergence to local minimal, excellent performance, and high stability. [26][27][28] Since the predictive and generalization capacity of SVR depends heavily on the proper selection of its hyper-parameters, this proposed model implements the gravitational search algorithm (GSA) developed recently for the optimal selection of SVR hyper-parameters.…”
