Minimal Partitions for p-norms of Eigenvalues
Virginie Bonnaillie-Noel, Beniamin Bogosel
In this article we are interested in studying partitions of the square, the disk and the equilateral triangle which minimize a p-norm of eigenvalues of the Dirichlet-Laplace operat…
Specific-heat exponent and modified hyperscaling in the 4D random-field Ising model
N. G. Fytas, V. Martin-Mayor, M. Picco +1
We report a high-precision numerical estimation of the critical exponent of the specific heat of the random-field Ising model in four dimensions. Our result indica…
Bayesian Modeling of Motion Perception using Dynamical Stochastic Textures
Jonathan Vacher, Andrew Isaac Meso, Laurent U. Perrinet +1
A common practice to account for psychophysical biases in vision is to frame them as consequences of a dynamic process relying on optimal inference with respect to a generative mod…
Inverse Problems with Invariant Multiscale Statistics
Ivan Dokmanić, Joan Bruna, Stéphane Mallat +1
We propose a new approach to linear ill-posed inverse problems. Our algorithm alternates between enforcing two constraints: the measurements and the statistical correlation structu…
Streaming k-mismatch with error correcting and applications
Jakub Radoszewski, Tatiana Starikovskaya
We present a new streaming algorithm for the -Mismatch problem, one of the most basic problems in pattern matching. Given a pattern and a text, the task is to find all substring…
Pairwise Quantization
Artem Babenko, Relja Arandjelović, Victor Lempitsky
We consider the task of lossy compression of high-dimensional vectors through quantization. We propose the approach that learns quantization parameters by minimizing the distortion…
