careful tuning. This pr... | http://arxiv.org/abs/2308.08495v1 |
Advances in Large Language Models (e.g., GPT-4, LLaMA) have improved the
generation of coherent sentences resembling human writing on a large scale,
resulting in the creation of so-called deepfake texts. However, this progress
poses security and privacy concerns, necessitating effective solutions for
distinguishing dee... | http://arxiv.org/abs/2304.01002v3 |
The critical heat flux (CHF) is an essential safety boundary in boiling heat
transfer processes employed in high heat flux thermal-hydraulic systems.
Identifying CHF is vital for preventing equipment damage and ensuring overall
system safety, yet it is challenging due to the complexity of the phenomena.
For an in-depth... | http://arxiv.org/abs/2305.02622v1 |
In this work, we investigate the effect of gravitational lensing on the
gravitational wave (GW) signals of a population of tidal disruption events
(TDEs). We estimate the number of lensed-magnified signals that we expect to
detect with future space-based GW observatories, in particular LISA and DECIGO.
We model the len... | http://arxiv.org/abs/2301.01804v2 |
Bayesian experimental design is a technique that allows to efficiently select
measurements to characterize a physical system by maximizing the expected
information gain. Recent developments in deep neural networks and normalizing
flows allow for a more efficient approximation of the posterior and thus the
extension of ... | http://arxiv.org/abs/2306.14510v1 |
Massive MIMO OFDM waveforms help support a large number of users in the same
time-frequency resource and also provide significant array gain for uplink
reception in cellular systems. However, channel estimation in such large
antenna systems can be tricky as pilot assignment for multiple users becomes
more challenging w... | http://arxiv.org/abs/2305.12431v2 |
In recent years, there has been tremendous progress in the development of
quantum computing hardware, algorithms and services leading to the expectation
that in the near future quantum computers will be capable of performing
simulations for natural science applications, operations research, and machine
learning at scal... | http://arxiv.org/abs/2307.05734v2 |
Although automatic speech recognition (ASR) can perform well in common
non-overlapping environments, sustaining performance in multi-talker
overlapping speech recognition remains challenging. Recent research revealed
that ASR model's encoder captures different levels of information with
different layers -- the lower la... | http://arxiv.org/abs/2302.09908v2 |
Due to the large number of submissions that more and more conferences
experience, finding an automatized way to well distribute the submitted papers
among reviewers has become necessary. We model the peer-reviewing matching
problem as a {\it bilevel programming (BP)} formulation. Our model consists of
a lower-level pro... | http://arxiv.org/abs/2307.12248v1 |
Regression testing is crucial in ensuring that pure code refactoring does not
adversely affect existing software functionality, but it can be expensive,
accounting for half the cost of software maintenance. Automated test case
generation reduces effort but may generate weak test suites. Test amplification
is a promisin... | http://arxiv.org/abs/2307.15527v1 |
Singing voice beat and downbeat tracking posses several applications in
automatic music production, analysis and manipulation. Among them, some require
real-time processing, such as live performance processing and
auto-accompaniment for singing inputs. This task is challenging owing to the
non-trivial rhythmic and harm... | http://arxiv.org/abs/2306.02372v1 |
From TESS photometry, 493 mid- to late-B stars with high frequencies (Maia
variables) have been identified. The distribution of projected rotational
velocities shows that the rotation rates of Maia variables are no different
from those of SPB stars. Moreover, many Maia stars pulsate with frequencies
exceeding 60 c/d. R... | http://arxiv.org/abs/2301.09280v1 |
