基于流形学习的正交稀疏保留投影
Orthogonal Sparsity Preserving Projections Based on Manifold Learning
摘要
Abstract
Sparsity Preserving Projections ( SPP) extracts features by preserving the global sparse reconstruction relations among samples, which achieves favorable classification results. However,the obtained transformation of SPP usually is not orthogonal,while in real appli-cations,orthogonality is advantageous for classification in many scenarios. Besides,according to the manifold learning theory,local mani-fold structure is more important than global Euclidean structure. Therefore,in this paper,introduce manifold preserving and orthogonal transformation into SPP,and propose two novel approaches for face and palmprint image feature extraction,which are Holistic Orthogonal Manifold and Sparsity Preserving Projections ( HOMSPP) and Iterative Orthogonal Manifold and Sparsity Preserving Projections ( IOM-SPP) .关键词
