News articles are driven by the informational sources journalists use in
reporting. Modeling when, how and why sources get used together in stories can
help us better understand the information we consume and even help journalists
with the task of producing it. In this work, we take steps toward this goal by
constructi... | http://arxiv.org/abs/2305.14904v1 |
As we enter the exascale computing era, efficiently utilizing power and
optimizing the performance of scientific applications under power and energy
constraints has become critical and challenging. We propose a low-overhead
autotuning framework to autotune performance and energy for various hybrid
MPI/OpenMP scientific... | http://arxiv.org/abs/2303.16245v1 |
Decision support systems for classification tasks are predominantly designed
to predict the value of the ground truth labels. However, since their
predictions are not perfect, these systems also need to make human experts
understand when and how to use these predictions to update their own
predictions. Unfortunately, t... | http://arxiv.org/abs/2306.03928v3 |
Beamforming (BF) training is crucial to establishing reliable millimeter-wave
communication connections between stations (STAs) and an access point. In IEEE
802.11ad BF training protocol, all STAs contend for limited BF training
opportunities, i.e., associated BF training (A-BFT) slots, which results in
severe collisio... | http://arxiv.org/abs/2301.01140v1 |
We review some uniqueness criteria for the Vlasov--Poisson system, emerging
as corollaries of stability estimates in strong or weak topologies, and show
how they serve as a guideline to solve problems arising in semiclassical
analysis. Different topologies allow to treat different classes of quantum
states. | http://arxiv.org/abs/2303.10634v1 |
Perturbative PT-symmetric quantum field theories with anti-Hermitian and
P-odd interaction terms are studied in path integral formalism and the i phi^3
model is calculated in detail. The nonlocal field transformation induced by the
C operator and corresponding transformations to Hermitian theories are given
systematica... | http://arxiv.org/abs/2305.05809v3 |
The concept of a recently proposed Forward-Forward learning algorithm for
fully connected artificial neural networks is applied to a single multi output
perceptron for classification. The parameters of the system are trained with
respect to increased (decreased) "goodness" for correctly (incorrectly)
labelled input sam... | http://arxiv.org/abs/2304.03189v1 |
Machine learning-based unfolding has enabled unbinned and high-dimensional
differential cross section measurements. Two main approaches have emerged in
this research area: one based on discriminative models and one based on
generative models. The main advantage of discriminative models is that they
learn a small correc... | http://arxiv.org/abs/2308.12351v2 |
We provide an updated 5 $^\prime $ $\times $ 5 $^\prime $ global geoid model
GGM2022, which is determined based on the shallow layer method (Shen method).
First, we choose an inner surface $\Gamma$ below the EGM2008 global geoid by 15
m, and the layer bounded by the inner surface $\Gamma$ and the Earth's
geographical s... | http://arxiv.org/abs/2306.15192v1 |
A number of labeling systems based on text have been proposed to help monitor
work on the United Nations (UN) Sustainable Development Goals (SDGs). Here, we
present a systematic comparison of systems using a variety of text sources and
show that systems differ considerably in their specificity (i.e., true-positive

The Watson-Crick complementary properties of DNA make DNA a useful tool for
the self-assembly of various target complexes. Concepts from graph theory can
be used to model the self-assembling process in which the vertices of the graph
represent $k$-armed branched junction molecules, called tiles. We seek to
determine th... | http://arxiv.org/abs/2302.13014v1 |
