Limit of the octahedron recurrence with GUE boundary data
Hariharan Narayanan
We study the tropical octahedron recurrence on the lattice tetrahedron with an intrinsic double-hive boundary law.…
Exposition of an approximation algorithm for mixed volumes of a constant number of convex bodies
Hariharan Narayanan
We study -relative approximation of mixed volumes of a fixed number of full-dimensional convex bodies in , given membership oracles and a known bound…
Hives from deformed GUE minor processes
Hariharan Narayanan
We construct random hives from deformed GUE minor processes. Starting from two independent diagonally deformed GUE matrices \[ X=\sqrt{n}(wG+uD),\qquad Y=\sqrt{n}(w'G'+u'D'), \] wh…
Denoising data using convex relaxations
Charles Fefferman, Aalok Gangopadhyay, Matti Lassas +2
We study the problem of denoising observations \(Y_i=X_i+Z_i\), where the latent variables \(X_i\) are sampled from a low-dimensional manifold in \(\mathbb{R}^n\) and the noise var…
