In this paper, we continue the research on the power of contextual grammars
with selection languages from subfamilies of the family of regular languages.
In the past, two independent hierarchies have been obtained for external and
internal contextual grammars, one based on selection languages defined by
structural prop... | http://arxiv.org/abs/2309.08724v1 |
In this paper, we show that the existence of a positive weak solution to the
equation $(-\Delta_g)^s u=f u^{-q(x)}\;\mbox{in}\; \Omega,$ where $\Omega$ is a
smooth bounded domain in $R^N$, $q\in C^1(\overline{\Omega})$, and
$(-\Delta_g)^s$ is the fractional $g$-Laplacian with $g$ is the antiderivative
of a Young functi... | http://arxiv.org/abs/2309.07417v1 |
This paper presents a bonobo detection and classification pipeline built from
the commonly used machine learning methods. Such application is motivated by
the need to test bonobos in their enclosure using touch screen devices without
human assistance. This work introduces a newly acquired dataset based on bonobo
record... | http://arxiv.org/abs/2309.03671v1 |
The vast majority of ASR research uses corpora in which both the training and
test data have been pre-segmented into utterances. In most real-word ASR
use-cases, however, test audio is not segmented, leading to a mismatch between
inference-time conditions and models trained on segmented utterances. In this
paper, we re... | http://arxiv.org/abs/2309.15013v1 |
Adversarial attacks dramatically change the output of an otherwise accurate
learning system using a seemingly inconsequential modification to a piece of
input data. Paradoxically, empirical evidence indicates that even systems which
are robust to large random perturbations of the input data remain susceptible
to small,... | http://arxiv.org/abs/2309.03665v2 |
In this paper, we present the details of Women in Computer Vision Workshop -
WiCV 2023, organized alongside the hybrid CVPR 2023 in Vancouver, Canada. WiCV
aims to amplify the voices of underrepresented women in the computer vision
community, fostering increased visibility in both academia and industry. We
believe that... | http://arxiv.org/abs/2309.12768v1 |
In this paper, we present an Eulerian-Lagrangian methodology to simulate the
interaction between a fluid-fluid interface and a solid particle in the
presence of wetting effects. The target physical problem is represented by
ternary phase systems in which a solid phase and a drop phase interact inside
an incompressible ... | http://arxiv.org/abs/2309.11261v1 |
The Regular Phantom Black Holes (RPBH)s are of theoretical and observational
importance, and some properties have been studied. In this work, we study some
of the thermodynamical properties such as entropy, and temperature, ... in
three asymptotically spacetimes: flat, de--Sitter (dS), and Anti-de Sitter
(AdS). Many of... | http://arxiv.org/abs/2308.16627v2 |
The Lattice Boltzmann Method (LBM), e.g. in [ 1] and [2 ], can be interpreted
as an alternative method for the numerical solution of partial differential
equations. Consequently, although the LBM is usually applied to solve fluid
flows, the above interpretation of the LBM as a general numerical tool, allows
the LBM to ... | http://arxiv.org/abs/2301.00228v1 |
This paper presents ContrastWSD, a RoBERTa-based metaphor detection model
that integrates the Metaphor Identification Procedure (MIP) and Word Sense
Disambiguation (WSD) to extract and contrast the contextual meaning with the
basic meaning of a word to determine whether it is used metaphorically in a
sentence. By utili... | http://arxiv.org/abs/2309.03103v2 |
Magnetic fields likely play an important role in star formation, but the
number of directly measured magnetic field strengths remains scarce. We
observed the 38.3 and 38.5 GHz Class II methanol (CH$_3$OH) maser lines toward
the high mass star forming region NGC 6334F for the Zeeman effect. The observed
spectral profile... | http://arxiv.org/abs/2309.15952v1 |
Change captioning aims to describe the difference between a pair of similar
images. Its key challenge is how to learn a stable difference representation
under pseudo changes caused by viewpoint change. In this paper, we address this
by proposing a self-supervised cross-view representation reconstruction
(SCORER) networ... | http://arxiv.org/abs/2309.16283v1 |
Feature preprocessing continues to play a critical role when applying machine
learning and statistical methods to tabular data. In this paper, we propose the
use of the kernel density integral transformation as a feature preprocessing
step. Our approach subsumes the two leading feature preprocessing methods as
limiting... | http://arxiv.org/abs/2309.10194v2 |
