5.1 Introduction and Use Cases

In Chapter 4, I discussed adaptive algorithms for the computation of the principal eigenvector of the online correlation matrix A_k∈ℜ^nXn. However, in some applications, it is not enough to just compute the principal eigenvector; we also need to compute the minor eigenvectors of A_k. One such application is multi-dimensional data compression or data dimensionality reduction in multimedia video transmission [Le Gall 91]. For example, in still video ...
