基于改进麻雀搜索算法-核极限学习机耦合算法的滑坡位移预测模型
Landslide Displacement Prediction Model Using Improved SSA-KELM Coupling Algorithm
【摘要】 传统的位移预测模型需要大量数据作为原始训练样本,一定程度上限制了预测模型的应用。为在有限的位移监测数据下进一步提高预测精度,针对金沙江沿岸某长期变形的滑坡体,采用麻雀搜索算法(sparrow search algorithm, SSA),结合核极限学习机算法(kernel-based extreme learning machine, KELM)算法,对滑坡的位移变化提出一种新的多变量位移预测方法,并与传统的支持向量机(support vector machine, SVM)进行对比,结果显示改进的SSA-KELM耦合滑坡预测模型比SVM模型预测精度更高,对金沙江沿岸地区的滑坡具有良好的位移预测效果。
【Abstract】 A large amount of data as original training samples is required for the traditional displacement prediction model, which limits the application of the prediction model to a certain extent. In order to further improve the prediction accuracy under the limited displacement monitoring data, a new multivariable displacement prediction method for landslide displacement was proposed, which combines the sparrow search algorithm(SSA) with the kernel-based extreme learning machine(KELM), aiming at a long-term deformation landslide around the Jinsha River. Compared with the traditional support vector machine(SVM), the results show that the novel model has higher prediction accuracy. It has a good prediction effect for landslide displacement along Jinsha River.
