WebApr 13, 2024 · We present a simple method to approximate the Fisher–Rao distance between multivariate normal distributions based on discretizing curves joining normal distributions and approximating the Fisher–Rao distances between successive nearby normal distributions on the curves by the square roots of their Jeffreys … Webis also a symmetric add(M)-approximation sequence, and thus theorem 1.1 applies. This paper is organized as follows. In § 2, we make some preparations, including the Φ-orbit construction, ghosts and coghosts. Sections 3 and 4 are devoted to proving theorem 1.1 and theorem 1.2, respectively. Some examples will be given in the final section. 2.

WebIn this paper, we present a refined convergence analysis for a simple yet powerful method for computing a symmetric low-rank orthogonal approximation of a symmetric tensor proposed in the literature. The significance is that the assumption guaranteeing the global convergence is vastly relaxed to only on an input parameter of this algorithm. WebSYMMETRIC AND GREEDY BASES FERNANDO ALBIAC, JOSE L.
