Reliability-Aware Multimodal Sentiment Prediction Under Local Modality Missingness
Minghao Kong, Deng Yao, Xi Zhang +4
Multimodal sentiment models are usually evaluated on complete utterances, yet streams often lose a contiguous span of text, audio, or video. We study local missingness on aligned C…
First-order -expansion for entropic optimal transport with non-degenerate costs
Luca Nenna, Brendan Pass, Paul Pegon +1
Entropy-regularized optimal transport (EOT) has become a key tool in optimal transport, providing both theoretical insight and efficient computation via the Sinkhorn algorithm. We…
A Rockafellar theorem for cyclically quasi-monotone maps: The regular non-vanishing case
Luigi De Pascale, Paul Pegon
In this paper, we study the connection between cyclic quasi-monotonicity and quasi-convexity, focusing on whether every cyclically quasi-monotone (possibly multi-valued) map is inc…
Convergence rates for regularized unbalanced optimal transport: the discrete case
Luca Nenna, Paul Pegon, Louis Tocquec
Unbalanced optimal transport (UOT) is a natural extension of optimal transport (OT) allowing comparison between measures of different masses. It arises naturally in machine learnin…
Optimal quantization with branched optimal transport distances
Paul Pegon, Mircea Petrache
We consider the problem of optimal approximation of a target measure by an atomic measure with atoms, in branched optimal transport distance. This is a new branched transport v…
Convergence rate of entropy-regularized multi-marginal optimal transport costs
Luca Nenna, Paul Pegon
We investigate the convergence rate of multi-marginal optimal transport costs that are regularized with the Boltzmann-Shannon entropy, as the noise parameter tends to…
Convergence rate of general entropic optimal transport costs
Guillaume Carlier, Paul Pegon, Luca Tamanini
We investigate the convergence rate of the optimal entropic cost to the optimal transport cost as the noise parameter . We show that for a…
Mass concentration in rescaled first order integral functionals
Antonin Monteil, Paul Pegon
We consider first order local minimization problems of the form under a mass constraint . We prove that the minimal…
Stability of optimal traffic plans in the irrigation problem
Maria Colombo, Antonio de Rosa, Andrea Marchese +2
We prove the stability of optimal traffic plans in branched transport. In particular, we show that any limit of optimal traffic plans is optimal as well. This is the Lagrangian cou…
On the Lagrangian branched transport model and the equivalence with its Eulerian formulation
Paul Pegon
First we present two classical models of Branched Transport: the Lagrangian model introduced by Bernot, Caselles, Morel, Maddalena, Solimini, and the Eulerian model introduced by X…
A fractal shape optimization problem in branched transport
Paul Pegon, Filippo Santambrogio, Qinglan Xia
We investigate the following question: what is the set of unit volume which can be best irrigated starting from a single source at the origin, in the sense of branched transport? W…
A kinetic selection principle for curl-free vector fields of unit norm
Pierre Bochard, Paul Pegon
This article is devoted to the generalization of results obtained in 2002 by Jabin, Otto and Perthame. In their article they proved that planar vector fields taking value into the…
Full characterization of optimal transport plans for concave costs
Paul Pegon, Davide Piazzoli, Filippo Santambrogio
This paper slightly improves a classical result by Gangbo and McCann (1996) about the structure of optimal transport plans for costs that are concave functions of the Euclidean dis…
Optimal transportation with an oscillation-type cost: the one-dimensional case
Didier Lesesvre, Paul Pegon, Filippo Santambrogio
The main result of this paper is the existence of an optimal transport map between two given measures and , for a cost which considers the maximal oscillation of at…
