PM2.5 Prediction of Innovation Priority Discrete Nonlinear Gray Model Based on Gray Wolf Optimization Algorithm

Journal of Advances in Mathematics and Computer Science, 2022
PM2.5 is one of the main factors of air pollution, so the prediction of PM2.5 is of great significance. For this reason, the innovation priority discrete nonlinear gray model based on gray wolf optimization algorithm is established, which is based on the innovation priority principle in the gray system principle.
