Missing Data Imputation in Bridge Health Monitoring System Based on the Support Vector Machine
摘要
Abstract
In bridge health monitoring system,data possess the features of small sample,nonlinear and sequential. A missing data imputation method based on the support vector machine is presented. It will analyse the autocorrelation of the data and choose the appropriate dimensions of the sample as inputs to the calculated mode which is given out by the principle of support vector regression machine. The model was utilized to forecast the missing data. Compared with the results of BP neural network's imputation, the experimental results of support vector machine in filling of missing data show that it has advantages on smaller samples and higher generalization ability.关键词
