Hamilton–Jacobi equations for finite-rank matrix inference [PDF]
The Annals of Applied Probability, 2020 We compute the large-scale limit of the free energy associated with the problem of inference of a finite-rank matrix. The method follows the principle put forward in arXiv:1811.01432 which consists in identifying a suitable Hamilton-Jacobi equation satisfied by the limit free energy.

Matrix valued Jacobi polynomials
Bulletin des Sciences Mathématiques, 2003 The author finds a matrix valued weight for Jacobi orthogonal polynomials, which satisfy an explicit differential equation of Jabobi type. An application to spherical functions is discussed. The Bochner problem of finding all families of orthogonal polynomials that are eigenfunctions of some second order differential operator is considered.

Convergence of Object Focused Simultaneous Estimation of Optical Flow and State Dynamics
International Journal of Advanced Robotic Systems, 2014 The purpose of this study is to prove the convergence of the simultaneous estimation of the optical flow and object state (SEOS) method. The SEOS method utilizes dynamic object parameter information when calculating optical flow in tracking a moving ...

Establishing Shape Correspondences: A Survey
Computer Graphics Forum, EarlyView.Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

Inversion of Jacobi's tridiagonal matrix
Computers & Mathematics with Applications, 1994 Explicit formulae are given for the elements of the inverse of a tridiagonal matrix (symmetric or not). The expressions contain elements of the original matrix, determinants of its principal minors and a related sequence of quantities defined inductively from the elements of the original matrix.

Jacobi Algorithm for Nonnegative Matrix Factorization with Transform Learning [PDF]
2018 26th European Signal Processing Conference (EUSIPCO), 2018 Nonnegative matrix factorization (NMF) is the state-of-the-art approach to unsupervised audio source separation. It relies on the factorization of a given short-time frequency transform into a dictionary of spectral patterns and an activation matrix.
