Therefore, forecasting gold great significance for investors, policy makers economists. In this paper, algorithm based on nonlinear weight decreasing PSO-SVR univariate time series prediction proposed price. can help firms to understand market trends fluctuations make more informed decisions. a weighted particle swarm (IPSO) optimised support vector machine (SVM) model, which trained with training set data validated using test data. Y-X scatter plots are plotted predicted real values set, line coordinate system, results show that able predict stock well, be very close each other, both set. model evaluation indexes R2, MAE, MBE MAPE do not deviate much from provide useful information decision enterprises.
