Processing related tasks. Thanks to their pre-training, they have been
successfully adapted to Information Extraction in business documents. However,
most pre-training tasks proposed in the literature for business documents are
too generic and not su... | http://arxiv.org/abs/2309.05429v1 |
A sequence $a_0<a_1<\ldots<a_n$ of nonnegative integers is called a Sidon
sequence if the sums of pairs $a_i+a_j$ are all different. In this paper we
construct CAT(0) groups and spaces from Sidon sequences. The arithmetic
condition of Sidon is shown to be equivalent to nonpositive curvature, and the
number of ways to r... | http://arxiv.org/abs/2309.14524v1 |
Evaluating the disruptive nature of academic ideas is a new area of research
evaluation that moves beyond standard citation-based metrics by taking into
account the broader citation context of publications or patents. The "$CD$
index" and a number of related indicators have been proposed in order to
characterise mathem... | http://arxiv.org/abs/2309.06120v1 |
In this paper we show how response function corrections to shear measurements
(e.g. as required by Metacalibration) propagate into cosmic shear power
spectra. We investigate a 2-sphere pixel (also known as HEALpixel') correction
and a forward-modelling approach using simple Gaussian simulations. In the
2-sphere pixel-c... | http://arxiv.org/abs/2302.14656v1 |
Moving animal groups transmit information through propagating waves or
behavioral cascades, exhibiting characteristics akin to systems near a critical
point from statistical physics. Using data from freely swimming schooling fish
in an experimental tank, we investigate spontaneous behavioral cascades
involving turning ... | http://arxiv.org/abs/2309.16455v3 |
Thouless charge pumping protocol provides an effective route for realizing
topological particle transport. To date, the first-order and higher-order
topological pumps, exhibiting transitions of edge-bulk-edge and
corner-bulk-corner states, respectively, are observed in a variety of
experimental platforms. Here, we prop... | http://arxiv.org/abs/2309.04051v1 |
In open multi-agent environments, the agents may encounter unexpected
teammates. Classical multi-agent learning approaches train agents that can only
coordinate with seen teammates. Recent studies attempted to generate diverse
teammates to enhance the generalizable coordination ability, but were
restricted by pre-defin... | http://arxiv.org/abs/2309.12633v1 |
The objective of this paper is to study the controllability of discrete-time
linear control systems in solvable Lie groups. In the special case of nilpotent
Lie groups, a necessary and sufficient condition for controllability is
established. Furthermore, the class of discrete-time linear systems in the
two-dimensional ... | http://arxiv.org/abs/2302.00145v6 |
Background: Dental caries diagnosis requires the manual inspection of
diagnostic bitewing images of the patient, followed by a visual inspection and
probing of the identified dental pieces with potential lesions. Yet the use of
artificial intelligence, and in particular deep-learning, has the potential to
aid in the di... | http://arxiv.org/abs/2310.00354v3 |
The Segmentation Anything Model (SAM) has gained significant attention for
its robust generalization capabilities across diverse downstream tasks.
However, the performance of SAM is noticeably diminished in medical images due
to the substantial disparity between natural and medical image domain. In this
paper, we prese... | http://arxiv.org/abs/2309.13539v3 |
One of the problems in quantitative finance that has received the most
attention is the portfolio optimization problem. Regarding its solving, this
problem has been approached using different techniques, with those related to
quantum computing being especially prolific in recent years. In this study, we
present a syste... | http://arxiv.org/abs/2309.12627v3 |
We present a nonlinear field theory of a three-sublattice hexagonal
antiferromagnet. The order parameter is the spin frame, an orthogonal triplet
of vectors related to sublattice magnetizations and spin chirality. The
exchange energy, quadratic in spin-frame gradients, has three coupling
constants, only two of which ma... | http://arxiv.org/abs/2307.16853v2 |
