Nonlinear robust partial least squares based on projection pursuit and its application
基于投影寻踪的非线性鲁棒偏最小二乘法及应用

Data from industrial field usually possess nonlinear feature and contain outliers;modeling with nonlinear partial least squares(PLS) method may suffer from these outliers. For this case, combining with radial basis function(RBF) networks, we present a nonlinear robust PLS method based on the projection pursuit. First, the nonlinear relationship between independent and dependent variables is changed into a linear one by RBF transformation. Then, projection pursuit algorithm is employed to extract the robust ...
