摘要: 针对开采沉陷量与多影响因素复杂非线性关系问题,提出了基于粒子群算法优化BP神经网络的Adaboost强预测模型(Adaboost-PSO-BP模型)。预测结果表明,与BP模型、Adaboost-BP模型和PSO-BP模型相比,Adaboost-PSO-BP模型提高了预测精度,平均相对误差值优化到4.26%|该模型融合了Adaboost算法侧重预测误差大的样本和粒子群算法优化神经网络权值及阈值的特点,实现了强预测器“优中选优”的目的,在开采沉陷预测中具有可行性。

Abstract: Aiming at the complex nonlinear relationship between mining subsidence and multiple influencing factors, an Adaboost strong prediction model (Adaboost-PSO-BP model) based on particle swarm optimization to optimize BP neural network is proposed. The prediction accuracy is improved, and the mean of the average relative error is optimized. The results shows that the strong prediction model combines the characteristics of the Adaboost algorithm with a large prediction error and the particle swarm algorithm to optimize the weights and thresholds of the neural network, which achieves the purpose of "optimizing the best" of the strong predictor, which confirms the Adaboost-PSO-BP The feasibility and practicability of strong prediction model in the prediction of mining subsidence.
