On Procrustes Analysis in Hyperbolic Space
Puoya Tabaghi, Ivan Dokmanic
Congruent Procrustes analysis aims to find the best matching between two point sets through rotation, reflection and translation. We formulate the Procrustes problem for hyperbolic…
Real Polynomial Gram Matrices Without Real Spectral Factors
Puoya Tabaghi, Ivan Dokmanić
It is well known that a non-negative definite polynomial matrix (a polynomial Gramian) can be written as a product of its polynomial spectral factors, .…
Geometric Invariants for Sparse Unknown View Tomography
Mona Zehni, Shuai Huang, Ivan Dokmanić +1
In this paper, we study a 2D tomography problem for point source models with random unknown view angles. Rather than recovering the projection angles, we reconstruct the model thro…
Kinetic Euclidean Distance Matrices
Puoya Tabaghi, Ivan Dokmanić, Martin Vetterli
Euclidean distance matrices (EDMs) are a major tool for localization from distances, with applications ranging from protein structure determination to global positioning and manifo…
