联合BEMD与LS-SVM的多波束异常数据探测方法
Detecting Outliers of Multibeam Sounding Data Based on BEMD and LS-SVM
摘要
Abstract
A method of detecting outlier of multibeam sounding based on BEMD and LSSVM is proposed for the nonlinear characteristics of multi-beam depth data.First,decompose the data into a number of functions in different frequencies using the method of BEMD;then,detect the outliers in IMF1 and IMF2 with the method of LSSVM;last,the outliers of original depth data was detected by the two outliers before.The feasibility of the method is proved by experiment,and better than the single model in defecting outliers.关键词
