Based on the Least Squares Support Vector Machines method, Incremental LS-SVM and Online LS-SVM method is proposed for identification of structural systems in this paper. It efficiently updates a trained LS-SVM by means of incremental and decremental pruning algorithms whenever a sample is added to, or removed from, the training set. The method overcomes the drawback of sparsenesslost within the standard LS-SVM and makes online training for the LS-SVM possible.

本文在最小二乘支持向量机方法的基础上提出了用于识别结构系统的增量最小二乘支持向量机和序贯最小二乘支持向量机方法，当新样本加入进来或老的样本被修剪下去的时候可以有效地更新，这种方法克服了标准最小二乘支持向量机方法的稀疏性缺失，使得结构参数的在线识别成为可能。
