We study the optimization problem of choosing strings of finite length to
maximize string submodular functions on string matroids, which is a broader
class of problems than maximizing set submodular functions on set matroids. We
provide a lower bound for the performance of the greedy algorithm in our
problem, and then ... | http://arxiv.org/abs/2308.15758v2 |
This paper studies a \emph{packing} problem in the so-called beyond-planar
setting, that is when the host graph is ``almost-planar'' in some sense.
Precisely, we consider the case that the host graph is $k$-planar, i.e., it
admits an embedding with at most $k$ crossings per edge, and focus on families
of $\Delta$-regul... | http://arxiv.org/abs/2301.01226v1 |
Cooperatively utilizing both ego-vehicle and infrastructure sensor data can
significantly enhance autonomous driving perception abilities. However,
temporal asynchrony and limited wireless communication in traffic environments
can lead to fusion misalignment and impact detection performance. This paper
proposes Feature... | http://arxiv.org/abs/2303.10552v1 |
This letter presents a novel hybrid method that leverages deep learning to
exploit the multi-resolution analysis capability of the wavelets, in order to
denoise a photoplethysmography (PPG) signal. Under the proposed method, a noisy
PPG sequence of length N is first decomposed into L detailed coefficients using
the fas... | http://arxiv.org/abs/2301.06549v1 |
Graph Neural Networks (GNNs) are a form of deep learning that enable a wide
range of machine learning applications on graph-structured data. The learning
of GNNs, however, is known to pose challenges for memory-constrained devices
such as GPUs. In this paper, we study exact compression as a way to reduce the
memory req... | http://arxiv.org/abs/2304.14793v1 |
It is shown that the extensions of exactly-solvable quantum mechanical
problems connected with the replacement of ordinary derivatives by Dunkl ones
and with that of classical orthogonal polynomials by exceptional orthogonal
ones can be easily combined. For such a purpose, the example of the Dunkl
oscillator on the lin... | http://arxiv.org/abs/2304.05846v2 |
If $k\geq 2$ is a positive integer, $\Omega \subset \mathbb{R}^{N}$ is a
domain then by the well-known properties of the Laplacian and the gradient, we
have \[
\Delta(f\cdot g)=g \Delta f+f \Delta g+2\langle \nabla f, \nabla g\rangle \]
for all $f, g\in \mathscr{C}^{k}(\Omega, \mathbb{R})$. Due to the results of
K\"o... | http://arxiv.org/abs/2306.02788v2 |
Real-world robotics applications demand object pose estimation methods that
work reliably across a variety of scenarios. Modern learning-based approaches
require large labeled datasets and tend to perform poorly outside the training
domain. Our first contribution is to develop a robust corrector module that
corrects po... | http://arxiv.org/abs/2302.06019v2 |
In sequential recommendation, multi-modal information (e.g., text or image)
can provide a more comprehensive view of an item's profile. The optimal stage
(early or late) to fuse modality features into item representations is still
debated. We propose a graph-based approach (named MMSR) to fuse modality
features in an a... | http://arxiv.org/abs/2308.15980v1 |
We study the time evolution of mean values of quantum operators in a regime
plagued by two difficulties: The smallness of $\hbar$ and the presence of
strong and ubiquitous classical chaos. While numerics become too
computationally expensive for purely quantum calculations as $\hbar \to 0$,
methods that take advantage o... | http://arxiv.org/abs/2308.04655v2 |
Deep reinforcement learning (RL) has shown promising results in robot motion
planning with first attempts in human-robot collaboration (HRC). However, a
fair comparison of RL approaches in HRC under the constraint of guaranteed
safety is yet to be made. We, therefore, present human-robot gym, a benchmark
suite for safe... | http://arxiv.org/abs/2310.06208v2 |
We calculate the balance function for charm in relativistic heavy-ion
collisions. The distribution of pairs of charm-anticharm quarks produced in
hard processes in the early stages of the nucleus-nucleus collision evolves in
the dense fireball formed in the collision. The evolution of the dense matter
is described usin... | http://arxiv.org/abs/2308.14446v2 |
The gravitational Stefan-Boltzmann law is considered for the Kerr black hole
in the weak-field limit. The energy-momentum tensor predicted by
Teleparallelism Equivalent to General Relativity (TEGR) is used in the Thermo
Field Dynamics (TFD) formalism to thermalize the field. A temperature-dependent
gravitational pressu... | http://arxiv.org/abs/2306.02950v1 |
