Support vector machine (SVM) is a novel and powerful learning method which is derived based on statistical learning theory (SLT) and the structural risk minimization principle. Traditional SVM only deals with the binary classification problems
however
there are large numbers of multi-classification problems in practical engineering. With a view to the main factors with important influence on sand liquefaction
multi-class support vector machines model based on clustering-binary tree is established. The nonlinear relationship between sand liquefaction and influencing factors is obtained from the finite empirical data by SVM. The results indicate that the structure of model base on SVM is reasonable; this algorithm is feasible; and it can predict the sand liquefaction more accurately.
