Abstract

It is hard to forecasting oil future prices accurately, which is affected by some nonlinear, nonstationary, and other chaotic characteristics. Then, a novel GA-SVR-GRNN hybrid deep learning algorithm is put forward for forecasting oil future price. First, a genetic algorithm (GA) is employed for optimizing parameters regarding the support vector regression machine (SVR), and the GA-SVR model is used to forecast oil future price. Further, a generalized regression neural network (GRNN) model is built for the residual series for forecasting. Finally, we obtain the predicted values of the oil future price series forecasted by the GA-SVR-GRNN hybrid deep learning algorithm. According to the simulation, the GA-SVR-GRNN hybrid deep learning algorithm achieves lower MSE, RMSE, MAE, and MAPE relative to the GRNN, GA-SVR, and PSO-SVR models, indicating that the proposed GA-SVR-GRNN hybrid deep learning algorithm can fully reveal the prediction advantages of the GA-SVR and GRNN models in the nonlinear space and is a more accurate and effective method for oil future price forecasting.

摘要

准确预测石油未来价格具有挑战性,因为它受到一些非线性、非平稳和其他混沌特征的影响。然后,提出了一种新的 GA-SVR-GRNN 混合深度学习算法来预测石油未来价格。首先,使用遗传算法(GA)优化支持向量回归机(SVR)的参数,然后使用 GA-SVR 模型预测石油未来价格。进一步,为残差序列构建广义回归神经网络(GRNN)模型进行预测。最后,我们得到了 GA-SVR-GRNN 混合深度学习算法预测的石油未来价格系列的预测值。根据模拟,GA-SVR-GRNN 混合深度学习算法的均方误差(MSE)、均方根误差(RMSE)、平均绝对误差(MAE)和平均绝对百分比误差(MAPE)均低于 GRNN、GA-SVR 和 PSO-SVR 模型,表明所提出的 GA-SVR-GRNN 混合深度学习算法可以充分揭示 GA-SVR 和 GRNN 模型在非线性空间中的预测优势,是一种更准确、有效的石油未来价格预测方法。
