Marvels and Pitfalls of the Langevin Algorithm in Noisy High-dimensional Inference
Stefano Sarao Mannelli, Giulio Biroli, Chiara Cammarota +3
Gradient-descent-based algorithms and their stochastic versions have widespread applications in machine learning and statistical inference. In this work we perform an analytic stud…
Jamming in multilayer supervised learning models
Silvio Franz, Sungmin Hwang, Pierfrancesco Urbani
Critical jamming transitions are characterized by an astonishing degree of universality. Analytic and numerical evidence points to the existence of a large universality class that…
Microscopic theory of two-step yielding in attractive colloids
Ada Altieri, Pierfrancesco Urbani, Francesco Zamponi
Attractive colloids display two distinct amorphous solid phases: the attractive glass, due to particle bonding, and the repulsive glass, due to the hard core repulsion. By means of…
Approximate Survey Propagation for Statistical Inference
Fabrizio Antenucci, Florent Krzakala, Pierfrancesco Urbani +1
Approximate message passing algorithm enjoyed considerable attention in the last decade. In this paper we introduce a variant of the AMP algorithm that takes into account glassy na…
Universality of jamming of non-spherical particles
Carolina Brito, Harukuni Ikeda, Pierfrancesco Urbani +2
Amorphous packings of non-spherical particles such as ellipsoids and spherocylinders are known to be hypostatic: the number of mechanical contacts between particles is smaller than…
Glassy nature of the hard phase in inference problems
Fabrizio Antenucci, Silvio Franz, Pierfrancesco Urbani +1
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…
A stability-reversibility map unifies elasticity, plasticity, yielding and jamming in hard sphere glasses
Yuliang Jin, Pierfrancesco Urbani, Francesco Zamponi +1
Amorphous solids, such as glasses, have complex responses to deformations, with significant consequences in material design and applications. In this respect two intertwined aspect…
