Given a probability measure $\mu$ on the unit circle $\mathbb{T}$, consider
the reproducing kernel $k_{\mu,n}(z_1, z_2)$ in the space of polynomials of
degree at most $n-1$ with the $L^2(\mu)$-inner product. Let $u, v \in
\mathbb{C}$. It is known that under mild assumptions on $\mu$ near $\zeta \in
\mathbb{T}$, the rat... | http://arxiv.org/abs/2306.13722v1 |
NA64 is a fixed target experiment at the CERN SPS designed as a hermetic
general purpose detector to search for Dark Sector physics in missing energy
events from electron/positron, hadrons, and muon scattering off nuclei. In this
contribution to the FIPs 2022 workshop, we review the current status and
prospects of NA64... | http://arxiv.org/abs/2301.09905v2 |
We revise the procedure proposed by Balassa to infer comparative advantage,
which is a standard tool, in Economics, to analyze specialization (of
countries, regions, etc.). Balassa's approach compares the export of a product
for each country with what would be expected from a benchmark based on the
total volumes of cou... | http://arxiv.org/abs/2304.12245v1 |
Explainability of Deep Neural Networks (DNNs) has been garnering increasing
attention in recent years. Of the various explainability approaches,
concept-based techniques stand out for their ability to utilize
human-meaningful concepts instead of focusing solely on individual pixels.
However, there is a scarcity of meth... | http://arxiv.org/abs/2306.03531v2 |
We formalize the notion of a sedentary vertex and present a relaxation of the
concept of a sedentary family of graphs introduced by Godsil [Linear Algebra
Appl. 614:356-375, 2021]. We provide sufficient conditions for a given vertex
in a graph to exhibit sedentariness. We also show that a vertex with at least
two twins... | http://arxiv.org/abs/2303.06297v3 |
We contribute to the vastly growing field of machine learning for engineering
systems by demonstrating that equivariant graph neural networks have the
potential to learn more accurate dynamic-interaction models than their
non-equivariant counterparts. We benchmark two well-studied fluid-flow systems,
namely 3D decaying... | http://arxiv.org/abs/2305.15603v1 |
Visual homing is a lightweight approach to visual navigation. Given the
stored information of an initial 'home' location, the navigation task back to
this location is achieved from any other location by comparing the stored home
information to the current image and extracting a motion vector. A challenge
that constrain... | http://arxiv.org/abs/2310.00906v1 |
The Skorokhod embedding problem (SEP) is to represent a given probability
measure as a Brownian motion $B$ at a particular stopping time. In recent years
particular attention has gone to solutions which exhibit additional optimality
properties due to applications to martingale inequalities and robust pricing in
mathema... | http://arxiv.org/abs/2307.03618v1 |
We aim to optimize the binary detection of Chronic Obstructive Pulmonary
Disease (COPD) based on emphysema presence in the lung with convolutional
neural networks (CNN) by exploring manually adjusted versus automated
window-setting optimization (WSO) on computed tomography (CT) images. 7,194 CT
images (3,597 with COPD;... | http://arxiv.org/abs/2303.07189v3 |
In this work, we present an explanation of the electric charge quantization
based on a semi-classical model of electrostatic fields. We claim that in
electrostatics, an electric charge must be equal to a rational multiple of the
elementary charge of an electron. However, the charge is quantized if the
system has certai... | http://arxiv.org/abs/2307.02506v1 |
We present a design framework called Conversational Learning with Analytical
Step-by-Step Strategies (CLASS) for building advanced Intelligent Tutoring
Systems (ITS) powered by high-performance Large Language Models (LLMs). The
CLASS framework empowers ITS with two key capabilities. First, through a
carefully curated s... | http://arxiv.org/abs/2305.13272v2 |
Motivated by applications in text mining and discrete distribution inference,
we investigate the testing for equality of probability mass functions of $K$
groups of high-dimensional multinomial distributions. A test statistic, which
is shown to have an asymptotic standard normal distribution under the null, is
proposed... | http://arxiv.org/abs/2301.01381v2 |
