Acoustic Event Classification (AEC) has been widely used in devices such as
smart speakers and mobile phones for home safety or accessibility support. As
AEC models run on more and more devices with diverse computation resource
constraints, it became increasingly expensive to develop models that are tuned
to achieve op... | http://arxiv.org/abs/2303.10351v1 |
We show that every element of $\mathrm{SL}_{n}(\mathbb{Z}/q\mathbb{Z})$ can
be lifted to an element of $\mathrm{SL}_{n}(\mathbb{Z})$ of norm at most
$Cq^2\log q$, while there exists an element such that every lift of it is of
norm at least $q^{2+o(1)}$. This should be compared to the recent result that
almost every ele... | http://arxiv.org/abs/2310.10269v1 |
Given a (smoothable) projective nodal K\"ahler Calabi-Yau threefold, we show,
via a gluing construction, that all its - possibly non-K\"ahler - small
resolutions admit Chern-Ricci flat balanced metrics, which among other things
solve the dilatino equation appearing in the Hull-Strominger system. | http://arxiv.org/abs/2301.11636v3 |
In recent years, there has been significant advancement in the field of model
watermarking techniques. However, the protection of image-processing neural
networks remains a challenge, with only a limited number of methods being
developed. The objective of these techniques is to embed a watermark in the
output images of... | http://arxiv.org/abs/2302.08637v1 |
While effective, the backpropagation (BP) algorithm exhibits limitations in
terms of biological plausibility, computational cost, and suitability for
online learning. As a result, there has been a growing interest in developing
alternative biologically plausible learning approaches that rely on local
learning rules. Th... | http://arxiv.org/abs/2308.02427v1 |
Learning-based solutions for vision tasks require a large amount of labeled
training data to ensure their performance and reliability. In single-task
vision-based settings, inconsistency-based active learning has proven to be
effective in selecting informative samples for annotation. However, there is a
lack of researc... | http://arxiv.org/abs/2306.12398v1 |
The field of artificial neural network (ANN) training has garnered
significant attention in recent years, with researchers exploring various
mathematical techniques for optimizing the training process. In particular,
this paper focuses on advancing the current understanding of gradient flow and
gradient descent optimiz... | http://arxiv.org/abs/2306.13086v1 |
Background: Studies have shown the potential adverse health effects, ranging
from headaches to cardiovascular disease, associated with long-term negative
emotions and chronic stress. Since many indicators of stress are imperceptible
to observers, the early detection and intervention of stress remains a pressing
medical... | http://arxiv.org/abs/2308.14245v1 |
Atom arrangement plays a critical role in determining material properties. It
is, therefore, essential for materials science and engineering to identify and
characterize distinct atom configurations. Currently, crystal structures can be
determined either by its static properties or by quantifying its structural
evoluti... | http://arxiv.org/abs/2310.11177v1 |
Integrating coded caching (CC) into multi-input multi-output (MIMO) setups
significantly enhances the achievable degrees of freedom (DoF). We consider a
cache-aided MIMO configuration with a CC gain $t$, where a server with $L$
Tx-antennas communicates with $K$ users, each equipped with $G$ Rx-antennas.
Similar to exis... | http://arxiv.org/abs/2304.13827v3 |
Time-dependent density functional theory continues to draw a large number of
users in a wide range of fields exploring myriad applications involving
electronic spectra and dynamics. Although in principle exact, the predictivity
of the calculations is limited by the available approximations for the
exchange-correlation ... | http://arxiv.org/abs/2302.11366v2 |
Many creative writing tasks (e.g., fiction writing) require authors to write
complex narrative components (e.g., characterization, events, dialogue) over
the course of a long story. Similarly, literary scholars need to manually
annotate and interpret texts to understand such abstract components. In this
paper, we explo... | http://arxiv.org/abs/2308.04056v1 |
We prove that any geometrically connected curve $X$ over a field $k$ is an
algebraic $K(\pi,1)$, as soon as its geometric irreducible components have
nonzero genus. This means that the cohomology of any locally constant
constructible \'etale sheaf of $\mathbb{Z}/n\mathbb{Z}$-modules, with $n$
invertible in $k$, is cano... | http://arxiv.org/abs/2306.03295v4 |
We demonstrate an ion acceleration scheme capable of simultaneously focusing
and accelerating a multispecies ion beam with monoenergetic spectra to a few
micron radius. The focal length and ion mean energy can be independently
controlled: the former by using a different front-surface shape and the latter
by tuning the ... | http://arxiv.org/abs/2310.08432v2 |
