An Improved BP Network Classifier Based on VPRS Feature Reduction
Mengxin Li, Chengdong Wu, Ying Zhang, Yong Yue · 2006
Variable precision rough sets (VPRS), as a extension of rough sets (RS) is adopted to reduce the redundant features for its ability of more useful information adopted compared with RS. The reduced features after VPRS are fed into the improved BP network proposed to inspect the defects of surface quality, which results in short training time and a high classification accuracy with a typical application in defect inspection of wood veneer
