Counting dense crowds through computer vision technology has attracted widespread
attention. Most crowd counting datasets use point annotations. In this paper, we formulate …

A bstract We establish that many fundamental concepts and techniques in quantum field
theory and collider physics can be naturally understood and unified through a simple new …

Which is the best metric for the space of collider events? Motivated by the success of the
energy mover's distance in characterizing collider events, we explore the larger space of …

A bstract Jet grooming is an important strategy for analyzing relativistic particle collisions in
the presence of contaminating radiation. Most jet grooming techniques introduce hard …

We consider the problem of finding an optimal transport plan between an absolutely
continuous measure and a finitely supported measure of the same total mass when the …

We study a model of crowd motion following a gradient vector field, with possibly additional
interaction terms such as attraction/repulsion, and we present a numerical scheme for its …

Persistence diagrams (PDs) are the most common descriptors used to encode the topology
of structured data appearing in challenging learning tasks; think eg of graphs, time series or …

The discrete element method (DEM) can provide detailed descriptions of sea ice dynamics
that explicitly model floes and discontinuities in the ice, which can be challenging to …

Many biological systems such as cell aggregates, tissues or bacterial colonies behave as
unconventional systems of particles that are strongly constrained by volume exclusion and …

In this article, we introduce a method to approximate solutions of some variational mean field
game problems with congestion by finite sets of player trajectories. These trajectories are …
