Low Residuals, Wrong Value: Learning the Viscosity Solution of Hamilton-Jacobi-Isaacs Equations with PINNs
Raul Jimenez, Pablo Tejerina-Pérez, Leonid Sarieddine +6
Physics-informed neural networks (PINNs) and other residual-trained solvers judge a candidate solution by the size of its sampled PDE residual. For first-order Hamilton-Jacobi equa…
Physics-Informed Neural Embeddings of PDE Solution Families
Raul Jimenez, Svitlana Mayboroda, Pavlos Protopapas +3
We introduce a physics-informed framework for learning finite-dimensional embeddings of solution families of partial differential equations. The method uses a multihead Physics-Inf…
Recovering Sharp Conductivity Features in the Finite-Data Calderón Problem with Physics-Informed Neural Networks
Ali AlHadi Kalout, Pablo Tejerina-Pérez, Konstantin Karchev +5
Physics-informed neural networks (PINNs) have recently emerged as a promising framework for addressing the Calderón inverse problem from limited boundary data. In this work, we rev…
THFM: A Unified Video Foundation Model for 4D Human Perception and Beyond
Letian Wang, Andrei Zanfir, Eduard Gabriel Bazavan +2
We present THFM, a unified video foundation model for human-centric perception that jointly addresses dense tasks (depth, normals, segmentation, dense pose) and sparse tasks (2d/3d…
Cluster glass behavior and magnetocaloric effect in the hexagonal polymorph of disordered CePdGe
Leszek S. Litzbarski, Kamil Balcarek, Anna Bajorek +3
In this work, we study the hexagonal variant of the system that crystallizes in the -type structure (space group , ) and exhib…
Learning embeddings of non-linear PDEs: the Burgers' equation
Pedro Tarancón-Álvarez, Leonid Sarieddine, Pavlos Protopapas +1
Embeddings provide low-dimensional representations that organize complex function spaces and support generalization. They provide a geometric representation that supports efficient…
The Atacama Cosmology Telescope: Constraints on Local Non-Gaussianity from the ACT Cluster Catalog
Leonid Sarieddine, J. Richard Bond, Matt Hilton +8
We derive constraints on local-type primordial non-Gaussianity using the ACT DR6 Sunyaev--Zel'dovich cluster catalog. Modeling the redshift- and mass-dependent number counts of 1,2…
Newtonian and Post-Newtonian Aspects of Mimetic Gravity
Leonid Sarieddine
Mimetic gravity is a modified theory of gravity which is able to incorporate dark matter into the underlying geometry of space-time by isolating the conformal degree of freedom. Th…
