partial differe... | http://arxiv.org/abs/2307.15325v2 |
The complex interplay between the Solar Wind and the lunar surface serves as
a quintessential example of space weathering. However, uncertainties persist
regarding the influence of plasma originating from Earth's ionosphere,
necessitating a comprehensive understanding of its quantitative impact.
Hitherto, the dearth of... | http://arxiv.org/abs/2309.15851v1 |
People can innately recognize human facial expressions in unnatural forms,
such as when depicted on the unusual faces drawn in cartoons or when applied to
an animal's features. However, current machine learning algorithms struggle
with out-of-domain transfer in facial expression recognition (FER). We propose
a biologic... | http://arxiv.org/abs/2304.02309v1 |
Past efforts to interrogate the mantle's contribution to Earth's topography
suffer from inadequate in-situ measurements of true bathymetry and the
involvement of an empirical plate model whose presumed lithospheric density
profile interferes with the interpretation of other mantle forces. Here, we
introduce a machine l... | http://arxiv.org/abs/2306.14312v1 |
Good frames were suggested in [Sh:h] as the (bare-bones) parallel, in the
context of AECs, to superstable (among elementary classes). Here we consider
$(\mu,\lambda,\kappa)$-frames as candidates for being (in the context of AECs)
the correct parallel to the class of $|T|^+$-saturated models of a strictly
stable theory ... | http://arxiv.org/abs/2305.02020v1 |
Few-shot question answering (QA) aims at precisely discovering answers to a
set of questions from context passages while only a few training samples are
available. Although existing studies have made some progress and can usually
achieve proper results, they suffer from understanding deep semantics for
reasoning out th... | http://arxiv.org/abs/2306.04101v1 |
Robust semantic segmentation of intraoperative image data could pave the way
for automatic surgical scene understanding and autonomous robotic surgery.
Geometric domain shifts, however, although common in real-world open surgeries
due to variations in surgical procedures or situs occlusions, remain a topic
largely unad... | http://arxiv.org/abs/2303.10972v2 |
The intrinsic alignment of galaxies is an important ingredient for modelling
weak-lensing measurements, and a potentially valuable cosmological and
astrophysical signal. In this paper, we present HYMALAIA: a new model to
predict the intrinsic alignments of biased tracers. HYMALAIA is based on a
perturbative expansion o... | http://arxiv.org/abs/2307.13754v2 |
This paper begins with a description of methods for estimating image
probability density functions that reflects the observation that such data is
usually constrained to lie in restricted regions of the high-dimensional image
space-not every pattern of pixels is an image. It is common to say that images
lie on a lower-... | http://arxiv.org/abs/2307.02881v5 |
In most conversations about explanation and AI, the recipient of the
explanation (the explainee) is suspiciously absent, despite the problem being
ultimately communicative in nature. We pose the problem `explaining AI systems'
in terms of a two-player cooperative game in which each agent seeks to maximise
our proposed ... | http://arxiv.org/abs/2305.12233v1 |
In this paper, first the full dynamics of aerial transportation of a rigid
body with arbitrary number of quadrotors is derived. Then a control strategy is
proposed to convey the nonuniform rigid body appropriately to the desired
trajectory. In the dynamical model of this transportation system, not only the
load is cons... | http://arxiv.org/abs/2305.09175v4 |
Outflow boundaries play an important role in multiphase fluid dynamics
simulations that involve transition between liquid and vapor phases. These
flows are dominated by low Weber numbers and a sharp jump in pressure,
velocity, and temperature. Inadequate treatment of these jumps at the outlet
generates undesirable flui... | http://arxiv.org/abs/2306.10174v4 |
Exploiting knowledge about the structure of a problem can greatly benefit the
efficiency and scalability of an Evolutionary Algorithm (EA). Model-Based EAs
(MBEAs) are capable of doing this by explicitly modeling the problem structure.
The Gene-pool Optimal Mixing Evolutionary Algorithm (GOMEA) is among the
state-of-th... | http://arxiv.org/abs/2305.06246v1 |
Within a modern democratic nation, elections play a significant role in the
nation's functioning. However, with the existing infrastructure for conducting
elections using Electronic Voting Systems (EVMs), many loopholes exist, which
illegitimate entities might leverage to cast false votes or even tamper with
the EVMs a... | http://arxiv.org/abs/2307.08412v1 |
The emergence of various notions of ``consistency'' in diffusion models has
garnered considerable attention and helped achieve improved sample quality,
likelihood estimation, and accelerated sampling. Although similar concepts have
been proposed in the literature, the precise relationships among them remain
unclear. In... | http://arxiv.org/abs/2306.00367v1 |
