Eigenvalues Eigenvectors Generalized principal component analysis (gpca) has been an active area of research in statistical signal processing for decades. it is used, e.g., for denoising in subspace tracking as the noise of different nature is incorporated into the procedure of maximizing signal to noise ratio (snr). this paper presents a fixed point approach concerning the principal generalized eigenvector extraction. Based on a gaussian mixture type model of k components, we derive eigen selection procedures that improve the usual spectral clustering algorithms in high dimensional settings, which typically act on the top few eigenvectors of an affinity matrix (e.g., x ⊤ x) derived from the data matrix x. our selection principle formalizes two intuitions. If we multiply v by a, then a sends v to a new vector av. if you can draw a line through the three points (0, 0), v and av, then av is just v multiplied by a number λ; that is, av = λv. in this case, we call λ an eigenvalue and v an eigenvector. for example, here (1, 2) is an eigvector and 5 an eigenvalue. av = (1 8 2 1) ⋅(1 2) = 5(1 2) = λv. In example 7.1.1, the values 10 and 0 are eigenvalues for the matrix a and we can label these as λ1 = 10 and λ2 = 0. when ax = λx for some x ≠ 0, we call such an x an eigenvector of the matrix a. the eigenvectors of a are associated to an eigenvalue. hence, if λ1 is an eigenvalue of a and ax = λ1x, we can label this eigenvector as x1.
