Unit testing is a commonly-used approach in software engineering to test the
correctness and robustness of written code. Unit tests are tests designed to
test small components of a codebase in isolation, such as an individual
function or method. Although unit tests have historically been written by human
programmers, r... | http://arxiv.org/abs/2310.00483v1 |
Fano varieties are basic building blocks in geometry - they are `atomic
pieces' of mathematical shapes. Recent progress in the classification of Fano
varieties involves analysing an invariant called the quantum period. This is a
sequence of integers which gives a numerical fingerprint for a Fano variety. It
is conjectu... | http://arxiv.org/abs/2309.05473v1 |
Online social media have become an important forum for exchanging political
opinions. In response to COVID measures citizens expressed their policy
preferences directly on these platforms. Quantifying political preferences in
online social media remains challenging: The vast amount of content requires
scalable automate... | http://arxiv.org/abs/2308.04444v1 |
We consider a version of the classical group testing problem motivated by PCR
testing for COVID-19. In the so-called tropical group testing model, the
outcome of a test is the lowest cycle threshold (Ct) level of the individuals
pooled within it, rather than a simple binary indicator variable. We introduce
the tropical... | http://arxiv.org/abs/2309.07264v2 |
An accurate motion model is a fundamental component of most autonomous
navigation systems. While much work has been done on improving model
formulation, no standard protocol exists for gathering empirical data required
to train models. In this work, we address this issue by proposing Data-driven
Robot Input Vector Expl... | http://arxiv.org/abs/2309.10718v2 |
The correlation between the sharpness of loss minima and generalisation in
the context of deep neural networks has been subject to discussion for a long
time. Whilst mostly investigated in the context of selected benchmark data sets
in the area of computer vision, we explore this aspect for the acoustic scene
classific... | http://arxiv.org/abs/2309.16369v2 |
The recent advancements in transformer-based visual trackers have led to
significant progress, attributed to their strong modeling capabilities.
However, as performance improves, running latency correspondingly increases,
presenting a challenge for real-time robotics applications, especially on edge
devices with comput... | http://arxiv.org/abs/2309.09249v1 |
We introduce logical synchrony, a framework that allows distributed computing
to be coordinated as tightly as in synchronous systems without the distribution
of a global clock or any reference to universal time. We develop a model of
events called a logical synchrony network, in which nodes correspond to
processors and... | http://arxiv.org/abs/2308.00144v3 |
Axions and axion-like particles (ALPs) are one of the most widely discussed
extensions of the Standard Model when it comes to the strong CP problem and
dark matter candidates. Current experiments are focused on the indirect
searches of invisible pseudoscalars in a wide parameter range. In this paper we
investigate limi... | http://arxiv.org/abs/2309.15106v2 |
We propose a new boson expansion method using a norm operator. The small
parameter expansion, in which the boson approximation becomes the zeroth-order
approximation, requires the double commutation relations between phonon
operators that are not closed between the phonon excitation modes adopted as
boson excitations. ... | http://arxiv.org/abs/2303.17986v2 |
In recent years, there is a growing interest in combining techniques
attributed to the areas of Statistics and Machine Learning in order to obtain
the benefits of both approaches. In this article, the statistical technique
lasso for variable selection is represented through a neural network. It is
observed that, althou... | http://arxiv.org/abs/2309.03770v1 |
Quantum amplification is recognized as a key resource for precision
measurements. However, most conventional paradigms employ an ensemble of
independent particles that usually limit the performance of quantum
amplification in gain, spectral linewidth, etc. Here we demonstrate a new
signal amplification using cooperativ... | http://arxiv.org/abs/2309.11374v1 |
