Surfing on minima of isostatic landscapes: avalanches and unjamming transition

no code implementations5 Oct 2020 Silvio Franz, Antonio Sclocchi, Pierfrancesco Urbani

This algorithm allows to "surf" between isostatic marginally stable configurations and to investigate some properties of such landscape.

We propose a new algorithm to learn the network of the interactions of pairwise Ising models.

Glassy nature of the hard phase in inference problems

no code implementations15 May 2018 Fabrizio Antenucci, Silvio Franz, Pierfrancesco Urbani, Lenka Zdeborová

An algorithmically hard phase was described in a range of inference problems: even if the signal can be reconstructed with a small error from an information theoretic point of view, known algorithms fail unless the noise-to-signal ratio is sufficiently small.
