night image annotations. Despite several domain adaptation methods, achieving
high-precision results remains an issue. False-positive error propagation is
still observed in methods using the well-established student-teacher framework,
particularly... | http://arxiv.org/abs/2303.13853v1 |
A reliable perception has to be robust against challenging environmental
conditions. Therefore, recent efforts focused on the use of radar sensors in
addition to camera and lidar sensors for perception applications. However, the
sparsity of radar point clouds and the poor data availability remain
challenging for curren... | http://arxiv.org/abs/2304.06547v1 |
We design and engineer Fast-Sparse-Spanner, a simple and practical (fast and
memory-efficient) algorithm for constructing sparse low stretch-factor
geometric graphs on large pointsets in the plane. To our knowledge, this is the
first practical algorithm to construct fast low stretch-factor graphs on large
pointsets wit... | http://arxiv.org/abs/2305.11312v1 |
Poisoning efficiency is crucial in poisoning-based backdoor attacks, as
attackers aim to minimize the number of poisoning samples while maximizing
attack efficacy. Recent studies have sought to enhance poisoning efficiency by
selecting effective samples. However, these studies typically rely on a proxy
backdoor injecti... | http://arxiv.org/abs/2306.08313v3 |
We provide a framework which admits a number of ``marginal'' sequential Monte
Carlo (SMC) algorithms as particular cases -- including the marginal particle
filter [Klaas et al., 2005, in: Proceedings of Uncertainty in Artificial
Intelligence, pp. 308--315], , the independent particle filter [Lin et al.,
2005, Journal o... | http://arxiv.org/abs/2303.03498v1 |
Point clouds arise from acquisition processes applied in various scenarios,
such as reverse engineering, rapid prototyping, or cultural preservation. To
run various simulations via, e.g., finite element methods, on the derived data,
a mesh has to be created from it. In this paper, a meshing algorithm for point
clouds i... | http://arxiv.org/abs/2305.07570v1 |
Monocular 3D object localization in driving scenes is a crucial task, but
challenging due to its ill-posed nature. Estimating 3D coordinates for each
pixel on the object surface holds great potential as it provides dense 2D-3D
geometric constraints for the underlying PnP problem. However, high-quality
ground truth supe... | http://arxiv.org/abs/2305.17763v1 |
Semi-Supervised image classification is one of the most fundamental problem
in computer vision, which significantly reduces the need for human labor. In
this paper, we introduce a new semi-supervised learning algorithm - SimMatchV2,
which formulates various consistency regularizations between labeled and
unlabeled data... | http://arxiv.org/abs/2308.06692v1 |
In nature, $\alpha$-quartz crystals frequently form contact twins - two
adjacent crystals with the same chemical structure but different
crystallographic orientation, sharing a common lattice plane. As
$\alpha$-quartz crystallises in a chiral space group, such twinning can occur
between enantiomorphs with the same hand... | http://arxiv.org/abs/2306.17227v1 |
Voltage control is crucial to large-scale power system reliable operation, as
timely reactive power support can help prevent widespread outages. However,
there is currently no built in mechanism for power systems to ensure that the
voltage control objective to maintain reliable operation will survive or
sustain the unc... | http://arxiv.org/abs/2305.16469v1 |
We apply the collective coordinate model framework to describe collisions of
a kink and an antikink with nonzero total momentum, i.e., when the solitons
possess different velocities. The minimal moduli space with only two
coordinates (the mutual distance and the position of the center of mass) is of
a wormhole type, wh... | http://arxiv.org/abs/2304.07895v2 |
The concept of tensor eigenpairs has received more researches in past
decades. Recent works have paid attentions to a special class of symmetric
tensors termed regular simplex tensors, which is constructed by equiangular
tight frame of n + 1 vectors in n-dimensional space, and the robustness of
eigenpairs was investiga... | http://arxiv.org/abs/2303.13847v1 |
The concept of mutual-visibility in graphs has been recently introduced. If
$X$ is a subset of vertices of a graph $G$, then vertices $u$ and $v$ are
$X$-visible if there exists a shortest $u,v$-path $P$ such that $V(P)\cap X
\subseteq \{u, v\}$. If every two vertices from $X$ are $X$-visible, then $X$
is a mutual-visi... | http://arxiv.org/abs/2307.10661v1 |
In the era of extensive intersection between art and Artificial Intelligence
(AI), such as image generation and fiction co-creation, AI for music remains
relatively nascent, particularly in music understanding. This is evident in the
limited work on deep music representations, the scarcity of large-scale
datasets, and ... | http://arxiv.org/abs/2306.10548v4 |
