Decentralized learning (DL) leverages edge devices for collaborative model
training while avoiding coordination by a central server. Due to privacy
concerns, DL has become an attractive alternative to centralized learning
schemes since training data never leaves the device. In a round of DL, all
nodes participate in mo... | http://arxiv.org/abs/2302.13837v2 |
Recent semantic segmentation models accurately classify test-time examples
that are similar to a training dataset distribution. However, their
discriminative closed-set approach is not robust in practical data setups with
distributional shifts and out-of-distribution (OOD) classes. As a result, the
predicted probabilit... | http://arxiv.org/abs/2305.09610v1 |
Muon-induced neutrons can lead to potentially irreducible backgrounds in rare
event search experiments. We have investigated the implication of laboratory
depth on the muon-induced background in a future dark matter experiment capable
of reaching the so-called neutrino floor. Our simulation study focused on a
xenon-bas... | http://arxiv.org/abs/2310.16586v1 |
We investigate the response of the micromechanical field-effect transistors
(MMFETs) to the impinging terahertz (THz) signals. The MMFET uses the
microcantilevers MC as a mechanically floating gate and the movable mirror of
the Michelson optical interferometer. The MC mechanical oscillations are
transformed into optica... | http://arxiv.org/abs/2306.13318v1 |
Positron emission tomography (PET) is an important functional medical imaging
technique often used in the evaluation of certain brain disorders, whose
reconstruction problem is ill-posed. The vast majority of reconstruction
methods in PET imaging, both iterative and deep learning, return a single
estimate without quant... | http://arxiv.org/abs/2306.04664v1 |
We construct strongly anisotropic quantum droplets with embedded vorticity in
the 3D space, with mutually perpendicular vortex axis and polarization of
atomic magnetic moments. Stability of these anisotropic vortex quantum droplets
(AVQDs) is verified by means of systematic simulations. Their stability area is
identifi... | http://arxiv.org/abs/2310.17840v3 |
In this work, we study face verification in datasets where images of the same
individuals exhibit significant age differences. This poses a major challenge
for current face recognition and verification techniques. To address this
issue, we propose a novel approach that utilizes multitask learning and a
Wasserstein dist... | http://arxiv.org/abs/2305.02745v1 |
In the work of Rostami et al., the Bogomolov multiplier of a Lie algebra $L$
over a field $\Omega$ is defined as a particular factor of a subalgebra of the
exterior product $L \wedge L$. If $L$ is finite dimensional, we identify this
object as a certain subgroup of the second cohomology group $H^2(L, \Omega)$ by
derivi... | http://arxiv.org/abs/2301.01963v1 |
We generalise various theorems for finding indiscernible trees and arrays to
positive logic: based on an existing modelling theorem for s-trees, we prove
modelling theorems for str-trees, str$_0$-trees (the reduct of str-trees that
forgets the length comparison relation) and arrays. In doing so, we prove
stronger versi... | http://arxiv.org/abs/2305.14127v2 |
Polar-optical phonon interactions with carriers in semiconductors are long
range interactions due to their Coulombic nature. Generally, if one wants to
treat these with non-equilibrium Green's functions, this long-range interaction
requires two- and three-particle Green's functions to be evaluated by e.g. the
Bethe-Sal... | http://arxiv.org/abs/2304.03772v1 |
Unmanned aerial vehicles (UAVs) are seen as a promising technology to perform
a wide range of tasks in wireless communication networks. In this work, we
consider the deployment of a group of UAVs to collect the data generated by IoT
devices. Specifically, we focus on the case where the collected data is
time-sensitive,... | http://arxiv.org/abs/2303.08680v1 |
ImageNet was famously created from Flickr image search results. What if we
recreated ImageNet instead by searching the massive LAION dataset based on
image captions alone? In this work, we carry out this counterfactual
investigation. We find that the resulting ImageNet recreation, which we call
LAIONet, looks distinctl... | http://arxiv.org/abs/2306.15769v1 |
