摘    要:针对神经网络的瓦斯预测模型存在的泛化性能差且存在易陷入局部最优的缺点,提出了基于最小二乘支持向量机(LS-SVM)时间序列瓦斯预测方法.由于标准最小二乘支持向量机(LS-SVM)要求样本误差分布服从高斯分布,且标准LS-SVM丧失鲁棒性与稀疏性等特点,提出了基于加权LS-SVM的瓦斯时间序列预测的方法,从而提高了标准L...

关 键 词:加权LS-SVM  时间序列  鲁棒性  瓦斯预测

Abstract:The neural network gas prediction model is poor in generalization performance and easy in falling into the local optimal value.In order to overcome these shortcomings,we propose the time series gas prediction method of least squares support vector machine(LS-SVM).However,in the LS-SVM case,the sparseness and robustness may lose,and the estimation of the support values is optimal only in the case of a Gaussian distribution of the error variables.So,this paper proposes the weighted LS-SVM to overcome these tw...
Keywords:weighted LS-SVM  time series  robustness  gas prediction
