We consider minimizing a smooth function subject to a summation constraint
over its variables. By exploiting a connection between the greedy 2-coordinate
update for this problem and equality-constrained steepest descent in the
1-norm, we give a convergence rate for greedy selection under a proximal

The study of the exchange of momentum and energy between wave components of
the turbulent velocity field, the so-called triad interactions, offers a unique
way of visualizing and describing turbulence. Most often, this study has been
carried out by Direct Numerical Simulations or by power spectral measurements.
Due to ... | http://arxiv.org/abs/2301.06588v2 |
Traditionally, data selection has been studied in settings where all samples
from prospective sources are fully revealed to a machine learning developer.
However, in practical data exchange scenarios, data providers often reveal only
a limited subset of samples before an acquisition decision is made. Recently,
there ha... | http://arxiv.org/abs/2307.02460v1 |
We present a high-density relativistic reflection analysis of 21 spectra of
six black hole X-ray binaries in the hard state with data from \textit{NuSTAR}
and \textit{Swift}. We find that 76\% of the observations in our sample require
a disk density higher than the 10$^{15}$~cm$^{-3}$ assumed in the previous
reflection... | http://arxiv.org/abs/2303.10593v2 |
This paper is concerned with a singular limit of the Kobayashi-Warren-Carter
system, a phase field system modelling the evolutions of structures of grains.
Under a suitable scaling, the limit system is formally derived when the
interface thickness parameter tends to zero. Different from many other
problems, it turns ou... | http://arxiv.org/abs/2306.15235v1 |
The essence of compiling with continuations is that conversion to
continuation-passing style (CPS) is equivalent to a source language
transformation converting to administrative normal form (ANF). Taking as source
language Moggi's computational lambda-calculus (lbc), we define an alternative
to the CPS-translation with... | http://arxiv.org/abs/2304.14752v1 |
Building error-corrected quantum computers relies crucially on measuring and
modeling noise on candidate devices. In particular, optimal error correction
requires knowing the noise that occurs in the device as it executes the
circuits required for error correction. As devices increase in size we will
become more relian... | http://arxiv.org/abs/2303.00780v1 |
Sports analytics benefits from recent advances in machine learning providing
a competitive advantage for teams or individuals. One important task in this
context is the performance measurement of individual players to provide reports
and log files for subsequent analysis. During sport events like basketball,
this invol... | http://arxiv.org/abs/2303.11855v1 |
We discuss the reactions $\pi p \to \pi p$ and $\pi p \to \pi p \gamma$ from
a general quantum field theory (QFT) point of view, describing these reactions
in QCD and lowest relevant order of electromagnetism. We consider the
pion-proton elastic scattering both off shell and on shell. The on-shell
amplitudes for $\pi^{... | http://arxiv.org/abs/2307.12673v2 |
The far-field channel model has historically been used in wireless
communications due to the simplicity of mathematical modeling and convenience
for algorithm design. With the need for high data rates, low latency, and
ubiquitous connectivity in the sixth generation (6G) of communication systems,
new technology enabler... | http://arxiv.org/abs/2308.15799v4 |
Subsurface imaging involves solving full waveform inversion (FWI) to predict
geophysical properties from measurements. This problem can be reframed as an
image-to-image translation, with the usual approach being to train an
encoder-decoder network using paired data from two domains: geophysical
property and measurement... | http://arxiv.org/abs/2305.13314v3 |
Data science has become increasingly essential for the production of official
statistics, as it enables the automated collection, processing, and analysis of
large amounts of data. With such data science practices in place, it enables
more timely, more insightful and more flexible reporting. However, the quality
and in... | http://arxiv.org/abs/2306.04338v1 |
