loci of some families of Finsler metrics of Randers type whose navigation data
is not a Killing ... | http://arxiv.org/abs/2309.11790v1 |
Recent experimental realization of the heteronuclear dipolar mixture of Dy
and Er atoms opens fascinating prospects for creating intriguing novel phases
in dipolar quantum gases. The experimentally measured value of intra-species
$s$-wave scattering length of $^{166}$Er condensate in a $^{164}$Dy-$^{166}$Er
mixture is ... | http://arxiv.org/abs/2309.16799v1 |
We propose DoE2Vec, a variational autoencoder (VAE)-based methodology to
learn optimization landscape characteristics for downstream meta-learning
tasks, e.g., automated selection of optimization algorithms. Principally, using
large training data sets generated with a random function generator, DoE2Vec
self-learns an i... | http://arxiv.org/abs/2304.01219v1 |
Isotopic anomalies provide a means of probing the materials responsible for
the formation of terrestrial planets. By analyzing new iron isotopic anomaly
data from Martian meteorites and drawing insights from published data for O,
Ca, Ti, Cr, Fe, Ni, Sr, Zr, Mo, Ru, and Si, we scrutinize potential changes in
the isotopi... | http://arxiv.org/abs/2309.15290v1 |
With the advent of large-scale pre-trained models, interest in adapting and
exploiting them for continual learning scenarios has grown.
In this paper, we propose an approach to exploiting pre-trained
vision-language models (e.g. CLIP) that enables further adaptation instead of
only using zero-shot learning of new tas... | http://arxiv.org/abs/2310.20348v1 |
We classify minimal surfaces $S$ with $p_g=q=2$ and $K_S^2=5$ or $6$. | http://arxiv.org/abs/2309.05097v2 |
Due to the implementation bottleneck of training data collection in realistic
wireless communications systems, supervised learning-based timing
synchronization (TS) is challenged by the incompleteness of training data. To
tackle this bottleneck, we extend the computer-aided approach, with which the
local device can gen... | http://arxiv.org/abs/2306.17570v1 |
The recent extremely bright gamma-ray burst (GRB), GRB 230307A from a binary
neutron star merger may offer a good probe for the production of GRB-neutrinos.
Within the constraint from IceCube neutrino non-detection, the limits for key
physical parameters of this burst are extracted in different scenarios
including the ... | http://arxiv.org/abs/2307.16547v7 |
In this paper, we explore zero- and few-shot generalization for fact
verification (FV), which aims to generalize the FV model trained on
well-resourced domains (e.g., Wikipedia) to low-resourced domains that lack
human annotations. To this end, we first construct a benchmark dataset
collection which contains 11 FV data... | http://arxiv.org/abs/2309.09444v1 |
Quantum interferometry based on induced-coherence phenomena has demonstrated
the possibility of undetected-photon measurements. Perturbation in the optical
path of probe photons can be detected by interference signals generated by
quantum mechanically correlated twin photons propagating through a different
path, possib... | http://arxiv.org/abs/2309.06777v1 |
Unsupervised learning allows us to leverage unlabelled data, which has become
abundantly available, and to create embeddings that are usable on a variety of
downstream tasks. However, the typical lack of interpretability of unsupervised
representation learning has become a limiting factor with regard to recent
transpar... | http://arxiv.org/abs/2309.16564v1 |
Lidar became an important component of the perception systems in autonomous
driving. But challenges of training data acquisition and annotation made
emphasized the role of the sensor to sensor domain adaptation. In this work, we
address the problem of lidar upsampling. Learning on lidar point clouds is
rather a challen... | http://arxiv.org/abs/2301.13558v1 |
A rapidly converging 4-dimensional Fourier shape parametrization is used to
model the fission process of heavy nuclei. Potential energy landscapes are
computed within the macroscopic-microscopic approach, on top of which the
multi-dimensional Langevin equation is solved to describe the fission dynamics.
Charge equilibr... | http://arxiv.org/abs/2309.09322v1 |
This document contains a detailed description of the STAR-loc dataset. For a
quick starting guide please refer to the associated Github repository
