Event cameras are neuromorphic vision sensors that record a scene as sparse
and asynchronous event streams. Most event-based methods project events into
dense frames and process them using conventional vision models, resulting in
high compu...

Adversarial attacks on deep-learning models have been receiving increased
attention in recent years. Work in this area has mostly focused on
gradient-based techniques, so-called "white-box" attacks, wherein the attacker
has access to the ta...

We obtain gradient estimates on solutions to parabolic Kolmogorov equation
with singular drift in a large class. Such estimates allow to construct a
Feller evolution family, which is used to construct unique weak solutions to
the correspond...
Resolutions of toric subvarieties by line bundles and applications

Mathematics
Algebraic Geometry
Given any toric subvariety Y of a smooth toric variety X of codimension
k, we construct a length k resolution of OY by line bundles on
X. Furthermore, these line bundles can all be chosen to be direct summands of
the p...

In this paper, we examine a modification of the Kazakov-Migdal (KM) model
with gauge group U(Nc), where the adjoint scalar fields in the conventional
KM model are replaced by Nf fundamental scalar fields (FKM model). After
tuning the ...

We investigate the properties of a family of polytopes that naturally arise
in connection with a problem in distributed data storage, namely service rate
region polytopes. The service rate region of a distributed coded system
describes the ...

reductive group G over a global field F, and obtain formulas, suitable for
computer calcul...
