resolves potential non-determinism. In this paper we propose an extension named
AHyperPCTL to a... | http://arxiv.org/abs/2307.05282v1 |
Black hole X-ray binaries (BHBs) offer insights into extreme gravitational
environments and the testing of general relativity. The X-ray spectrum
collected by NICER offers valuable information on the properties and behaviour
of BHBs through spectral fitting. However, traditional spectral fitting methods
are slow and sc... | http://arxiv.org/abs/2310.17249v2 |
Content-based fashion image retrieval (CBFIR) has been widely used in our
daily life for searching fashion images or items from online platforms. In
e-commerce purchasing, the CBFIR system can retrieve fashion items or products
with the same or comparable features when a consumer uploads a reference image,
image with t... | http://arxiv.org/abs/2303.17371v1 |
In-context learning (ICL) is an important paradigm for adapting large
language models (LLMs) to new tasks, but the generalization behavior of ICL
remains poorly understood. We investigate the inductive biases of ICL from the
perspective of feature bias: which feature ICL is more likely to use given a
set of underspecif... | http://arxiv.org/abs/2305.13299v1 |
Machine learning techniques are effective for building predictive models
because they identify patterns in large datasets. Development of a model for
complex real-life problems often stop at the point of publication, proof of
concept or when made accessible through some mode of deployment. However, a
model in the medic... | http://arxiv.org/abs/2303.01513v3 |
Artificial intelligence is constantly evolving and can provide effective help
in all aspects of people's lives. The experiment is mainly to study the use of
artificial intelligence in the field of medicine. The purpose of this
experiment was to compare which of MobileNetV1 and MobileNetV2 models was
better at detecting... | http://arxiv.org/abs/2308.03076v1 |
Federated Learning (FL) allows several clients to construct a common global
machine-learning model without having to share their data. FL, however, faces
the challenge of statistical heterogeneity between the client's data, which
degrades performance and slows down the convergence toward the global model. In
this paper... | http://arxiv.org/abs/2308.13265v2 |
The neutron optical Lloyd interferometer can serve as a potent experiment for
probing fundamental physics beyond the standard models of particles and
cosmology. In this article, we provide a full Green's function analysis of a
Lloyd interferometer in the limit that the reflecting mirror extends to the
screen. We consid... | http://arxiv.org/abs/2302.11429v2 |
This paper presents an empirical exploration of non-transitivity in
perfect-information games, specifically focusing on Xiangqi, a traditional
Chinese board game comparable in game-tree complexity to chess and shogi. By
analyzing over 10,000 records of human Xiangqi play, we highlight the existence
of both transitive a... | http://arxiv.org/abs/2308.04719v1 |
The study of the early phases of star and planet formation is important to
understand the physical and chemical history of stellar systems such as our
own. In particular, protostars born in rich clusters are prototypes of the
young Solar System. In the framework of the Seeds Of Life In Space (SOLIS)
large observational... | http://arxiv.org/abs/2301.10267v1 |
Multilingual language models enable zero-shot cross-lingual transfer
(ZS-XLT): fine-tuned on sizable source-language task data, they perform the
task in target languages without labeled instances. The effectiveness of ZS-XLT
hinges on the linguistic proximity between languages and the amount of
pretraining data for a l... | http://arxiv.org/abs/2310.10532v1 |
In this paper we develop a linear expectile hidden Markov model for the
analysis of cryptocurrency time series in a risk management framework. The
methodology proposed allows to focus on extreme returns and describe their
temporal evolution by introducing in the model time-dependent coefficients
evolving according to a... | http://arxiv.org/abs/2301.09722v2 |
In this paper, we lay out a vision for analysing semantic trajectory traces
and generating synthetic semantic trajectory data (SSTs) using generative
language model. Leveraging the advancements in deep learning, as evident by
progress in the field of natural language processing (NLP), computer vision,
etc. we intend to... | http://arxiv.org/abs/2306.13905v1 |
