Diffusion models generate highly realistic images by learning a multi-step
denoising process, naturally embodying the principles of multi-task learning
(MTL). Despite the inherent connection between diffusion models and MTL, there
remains an unexplored area in designing neural architectures that explicitly
incorporate ... | http://arxiv.org/abs/2310.07138v3 |
We present a novel cold strontium atom source designed for quantum sensors.
We optimized the deceleration process to capture a large velocity class of
atoms emitted from an oven and achieved a compact and low-power setup capable
of generating a high atomic flux. Our approach involves velocity-dependent
transverse captu... | http://arxiv.org/abs/2310.00657v2 |
Traces of large powers of real-valued Wigner matrices are known to have
Gaussian fluctuations: for $A=\frac{1}{\sqrt{n}}(a_{ij})_{1 \leq i,j \leq n}\in
\mathbb{R}^{n \times n}, A=A^T$ with $(a_{ij})_{1 \leq i \leq j \leq n}$
i.i.d., symmetric, subgaussian, $\mathbb{E}[a^{2}_{11}]=1,$ and $p=o(n^{2/3}),$
as $n,p \to \in... | http://arxiv.org/abs/2305.04687v1 |
The prevailing statistical approach to analyzing persistence diagrams is
concerned with filtering out topological noise. In this paper, we adopt a
different viewpoint and aim at estimating the actual distribution of a random
persistence diagram, which captures both topological signal and noise. To that
effect, Chazel a... | http://arxiv.org/abs/2310.11982v2 |
This paper presents a novel first-order mean-field game model that includes a
prescribed incoming flow of agents in part of the boundary (Neumann boundary
condition) and exit costs in the remaining portion (Dirichlet boundary
condition). Our model is described by a system of a Hamilton-Jacobi equation
and a stationary ... | http://arxiv.org/abs/2305.15952v1 |
In this position paper, we argue that the classical evaluation on Natural
Language Processing (NLP) tasks using annotated benchmarks is in trouble. The
worst kind of data contamination happens when a Large Language Model (LLM) is
trained on the test split of a benchmark, and then evaluated in the same
benchmark. The ex... | http://arxiv.org/abs/2310.18018v1 |
We demonstrate that it is possible to test models of gravity, such as
Palatini $f(R)$ and Eddington-inspired Born-Infeld models, using seismic data
from Earth. By incorporating additional limitations on Earth's moment of
inertia and mass given from observational data, the models' parameters can be
restricted to a $2\si... | http://arxiv.org/abs/2303.17213v2 |
Quantum correlations and nonclassical states are at the heart of emerging
quantum technologies. Efforts to produce long-lived states of such quantum
resources are a subject of tireless pursuit. Among several platforms useful for
quantum technology, the mature quantum system of light-matter interactions
offers unprecede... | http://arxiv.org/abs/2309.02123v1 |
In finite-dimensional simple Lie algebras and affine Kac-Moody Lie algebras,
Chevalley involutions are crucial ingredients of the modular theory. Towards
establishing the modular theory for extended affine Lie algebras, we
investigate the existence of ``Chevalley involutions" for Lie tori and extended
affine Lie algebr... | http://arxiv.org/abs/2302.00446v2 |
Extreme mechanical processes such as strong lattice distortion and bond
breakage during fracture are ubiquitous in nature and engineering, which often
lead to catastrophic failure of structures. However, understanding the
nucleation and growth of cracks is challenged by their multiscale
characteristics spanning from at... | http://arxiv.org/abs/2310.19306v1 |
Subband-based approaches process subbands in parallel through the model with
shared parameters to learn the commonality of local spectrums for noise
reduction. In this way, they have achieved remarkable results with fewer
parameters. However, in some complex environments, the lack of global spectral
information has a n... | http://arxiv.org/abs/2305.05599v1 |
Despite recent advances of layered square-net topological material models
that possess ideal semimetallic electronic structures and promising potential
in material applications, the identification of experimentally accessible
two-dimensional square-net materials with related topological properties has
proven challengin... | http://arxiv.org/abs/2304.14965v2 |
4D seismic inversion is the leading method to quantitatively monitor fluid
flow dynamics in the subsurface, with applications ranging from enhanced oil
recovery to subsurface CO2 storage. The process of inverting seismic data for
reservoir properties is, however, a notoriously ill-posed inverse problem due
to the band-... | http://arxiv.org/abs/2303.11662v1 |
