摘要:Abstract(#br)In this note, we show that the mathematical formulation of the two-dimensional discriminant locality preserving projections (2D-DLPP) proposed in the paper [R. Zhi, Q. Ruan, Facial expression recognition based on two-dimensional discriminant locality preserving ...

摘要:Abstract(#br)In this note, from another point of view and in a more general situation, we formulate an EM algorithm for finding the leading eigen-system of any positive semi-definite matrix in a very simple derivation. The proposed EM approach can directly compute not only the ei...

摘要:Abstract(#br)Generalized discriminant analysis (GDA) has provided an extremely powerful approach to extracting nonlinear features via kernel trick. And it has been suggested for a number of applications, such as classification problem. Whereas the GDA could be solved by the ...
