Inference in conditioned dynamics through causality restoration

1 code implementation18 Oct 2022 Alfredo Braunstein, Giovanni Catania, Luca Dall'Asta, Matteo Mariani, Anna Paola Muntoni

Computing observables from conditioned dynamics is typically computationally hard, because, although obtaining independent samples efficiently from the unconditioned dynamics is usually feasible, generally most of the samples must be discarded (in a form of importance sampling) because they do not satisfy the imposed conditions.

A Bayesian generative neural network framework for epidemic inference problems

2 code implementations5 Nov 2021 Indaco Biazzo, Alfredo Braunstein, Luca Dall'Asta, Fabio Mazza

The reconstruction of missing information in epidemic spreading on contact networks can be essential in the prevention and containment strategies.

Loop corrections in spin models through density consistency

1 code implementation24 Oct 2018 Alfredo Braunstein, Giovanni Catania, Luca Dall'Asta

Computing marginal distributions of discrete or semidiscrete Markov random fields (MRFs) is a fundamental, generally intractable problem with a vast number of applications in virtually all fields of science.
