characteristics of the MSPs, and search for previously unknown sources of
interest. The MSPs ex... | http://arxiv.org/abs/2307.02077v1 |
Launched on December 9, 2021, the Imaging X-ray Polarimetry Explorer (IXPE)
is the first imaging polarimeter ever flown, providing sensitivity in the 2--8
keV range, and during the 2-year initial phase of the mission will sample tens
of X-ray sources among different source classes. While most of the measurements
will b... | http://arxiv.org/abs/2303.10184v1 |
Lattice QCD offers the possibility of computing parton distributions from
first principles, although not in the usual $\overline{MS}$ factorization
scheme. We study in this paper the evolution of non-singlet parton distribution
functions (PDFs) in the short-distance factorization scheme which notably
arises in lattice ... | http://arxiv.org/abs/2310.19926v1 |
Previous work has established that RNNs with an unbounded activation function
have the capacity to count exactly. However, it has also been shown that RNNs
are challenging to train effectively and generally do not learn exact counting
behaviour. In this paper, we focus on this problem by studying the simplest
possible ... | http://arxiv.org/abs/2304.03639v1 |
Visual perception is an important component for autonomous navigation of
unmanned surface vessels (USV), particularly for the tasks related to
autonomous inspection and tracking. These tasks involve vision-based navigation
techniques to identify the target for navigation. Reduced visibility under
extreme weather condit... | http://arxiv.org/abs/2308.04283v1 |
Sequential Bayesian inference can be used for continual learning to prevent
catastrophic forgetting of past tasks and provide an informative prior when
learning new tasks. We revisit sequential Bayesian inference and test whether
having access to the true posterior is guaranteed to prevent catastrophic
forgetting in Ba... | http://arxiv.org/abs/2301.01828v2 |
Galactic supernova remnants (SNRs) play an important role in our
understanding of supernovae and their feedback on the interstellar environment.
SNR G352.7$-$0.1 is special for its thermal composite morphology and
double-ring structure. We have performed spectroscopic mapping in $^{12}$CO and
$^{13}$CO $J=2$-1 lines to... | http://arxiv.org/abs/2307.03369v2 |
This paper focuses on predicting the occurrence of grokking in neural
networks, a phenomenon in which perfect generalization emerges long after signs
of overfitting or memorization are observed. It has been reported that grokking
can only be observed with certain hyper-parameters. This makes it critical to
identify the... | http://arxiv.org/abs/2306.13253v3 |
Superadiabatic dynamical density functional theory (superadiabatic-DDFT), a
first-principles approach based on the inhomogeneous two-body correlation
functions, is employed to investigate the response of interacting Brownian
particles to time-dependent external driving. Predictions for the
superadiabatic dynamics of th... | http://arxiv.org/abs/2304.05248v2 |
We investigate the mechanisms behind the quasi-periodic outbursts on the
Covid-19 epidemics. Data for France and Germany show that the patterns of
outbursts exhibit a qualitative change in early 2022, which appears in a change
in their average period, and which is confirmed by time-frequency analysis.
This provides a s... | http://arxiv.org/abs/2308.14090v2 |
Remote collaborative work has become pervasive in many settings, from
engineering to medical professions. Users are immersed in virtual environments
and communicate through life-sized avatars that enable face-to-face
collaboration. Within this context, users often collaboratively view and
interact with virtual 3D model... | http://arxiv.org/abs/2302.07909v1 |
We study how in-context learning (ICL) in language models is affected by
semantic priors versus input-label mappings. We investigate two setups-ICL with
flipped labels and ICL with semantically-unrelated labels-across various model
families (GPT-3, InstructGPT, Codex, PaLM, and Flan-PaLM). First, experiments
on ICL wit... | http://arxiv.org/abs/2303.03846v2 |
As artificial intelligence (AI) models continue to scale up, they are
becoming more capable and integrated into various forms of decision-making
systems. For models involved in moral decision-making, also known as artificial
moral agents (AMA), interpretability provides a way to trust and understand the
agent's interna... | http://arxiv.org/abs/2307.00660v1 |
We construct the first asymptotically good relaxed locally correctable codes
with polylogarithmic query complexity, bringing the upper bound polynomially
close to the lower bound of Gur and Lachish (SICOMP 2021). Our result follows
from showing that a high-rate locally testable code can boost the block length
of a smal... | http://arxiv.org/abs/2306.17035v2 |
