Improved sparse PCA method for face and image recognition

no code implementations1 Dec 2021 Loc Hoang Tran, Tuan Tran, An Mai

Experimental results illustrate that the accuracy of the combination of the sparse PCA method (using the proximal gradient method and the FISTA method) and one specific classification system may be lower than the accuracy of the combination of the PCA method and one specific classification system but sometimes the combination of the sparse PCA method (using the proximal gradient method or the FISTA method) and one specific classification system leads to better accuracy.
