Adaptive Supervised Discriminant Projection

Considering the weakness of Unsupervised Discriminant Projection (UDP), a novel feature extraction algorithm, termed Adaptive Supervised Discriminant Projection Analysis (ASDP), is proposed in the paper. The proposed algorithm does not only integrate a kind of dynamic feedback mechanism into construction of scatter matrices but also make full use of the class label information. The experimental results on AR and FERET face databases show the proposed method is more effective than some existing feature extraction methods such as UDP, LDA, etc.
