RESEARCH ON FAULT DIAGNOSIS METHOD BASED ON NEIGHBORHOOD ADAPTIVE LLTSA FOR DIMENSION REDUTION

In order to solve interference of the neighborhood size of the linear local tangent space alignment（ LLTSA） when used in fault feature reduction,in this paper,a fault diagnosis method based on linear local tangent space alignment（ NALLTSA） for dimension reduction is proposed. Firstly,the high-dimens...
