The BeMi Stardust: a Structured Ensemble of Binarized Neural Networks

no code implementations7 Dec 2022 Ambrogio Maria Bernardelli, Stefano Gualandi, Hoong Chuin Lau, Simone Milanesi

While the previous approaches achieve an average accuracy of 51. 1% on the MNIST dataset, the BeMi ensemble achieves an average accuracy of 61. 7% when trained with 10 images per class and 76. 4% when trained with 40 images per class.

A kinetic description of the body size distributions of species

no code implementations1 Jun 2022 Stefano Gualandi, Giuseppe Toscani, Eleonora Vercesi

In this paper, by resorting to classical methods of statistical mechanics, we build a kinetic model able to reproduce the observed statistical weight distribution of many diverse species.

The Gene Mover's Distance: Single-cell similarity via Optimal Transport

no code implementations1 Feb 2021 Riccardo Bellazzi, Andrea Codegoni, Stefano Gualandi, Giovanna Nicora, Eleonora Vercesi

In the Optimal Transport model, we use two types of cost function for measuring the distance between a pair of genes.

The Equivalence of Fourier-based and Wasserstein Metrics on Imaging Problems

no code implementations13 May 2020 Gennaro Auricchio, Andrea Codegoni, Stefano Gualandi, Giuseppe Toscani, Marco Veneroni

We investigate properties of some extensions of a class of Fourier-based probability metrics, originally introduced to study convergence to equilibrium for the solution to the spatially homogeneous Boltzmann equation.

Computing Kantorovich-Wasserstein Distances on d-dimensional histograms using (d+1)-partite graphs

no code implementations NeurIPS 2018 Gennaro Auricchio, Federico Bassetti, Stefano Gualandi, Marco Veneroni

This paper presents a novel method to compute the exact Kantorovich-Wasserstein distance between a pair of $d$-dimensional histograms having $n$ bins each.

1 code implementation NeurIPS 2018 Gennaro Auricchio, Federico Bassetti, Stefano Gualandi, Marco Veneroni

This paper presents a novel method to compute the exact Kantorovich-Wasserstein distance between a pair of $d$-dimensional histograms having $n$ bins each.

On the Computation of Kantorovich-Wasserstein Distances between 2D-Histograms by Uncapacitated Minimum Cost Flows

3 code implementations2 Apr 2018 Federico Bassetti, Stefano Gualandi, Marco Veneroni

When the distance among bins is measured with the 2-norm: (i) we derive a quantitative estimate on the error between optimal and approximate solution; (ii) given the error, we construct a reduced flow network of size $O(n)$.
