Estimation with Quantized Parameter Side-Information
Mathis Wetterwald, Ofer Shayevitz, Michèle Wigger
This paper presents upper and lower bounds on the minimax risk of a parameter estimation problem where the estimator not only observes independent and identically distributed obser…
Spanners and Hybrid Spanners with Nearly Tight Bounds
Shiri Chechik, Gur Lifshitz
For an -vertex undirected, unweighted graph and a positive integer , we present new spanner constructions with edges that achieve nearly optimal gu…
Kernel Reboot: Breaking the Boundaries of Neural Tangent Kernels for Neural Fields
Amir Mallak, Alaa Maalouf, Lior Wolf +2
Neural fields (NFs) map continuous coordinates to signals such as color or density, but fast high-quality reconstruction from sparse observations remains difficult. Classical Neura…
Dipole-dipole scattering at high energy in the Pomeron field theory with Braun Hamiltonian and beyond
Eugene Levin
In this paper we find that the scattering matrix for dipole-dipole interaction in the saturation region has the form: ${\cal S}^d_d \xrightarrow{z \,\gg\,1} \exp\Lb - C^d_d z^2\Rb…
Realistic Counterfactual Explanations via Denial Constraints
Avia Asael, Nave Frost, Amir Gilad +1
In the realm of Explainable AI, classification results are often explained via counterfactuals (CFs for short), which are (ideally small) perturbations to an instance that lead to…
Entanglement breaking in self-referential quantum feedback: a record bound and an exactly solvable loop
Eran Kopel
A feedback loop that returns a message into the process it describes defines a quantum channel on the message. We ask when such a loop preserves entanglement with a reference, that…
