In this paper, we address the problem of modeling data with periodic
autoregressive (PAR) time series and additive noise. In most cases, the data
are processed assuming a noise-free model (i.e., without additive noise), which
is not a realistic assumption in real life. The first two steps in PAR model
identification ar... | http://arxiv.org/abs/2308.11265v2 |
Medical segmentation models are evaluated empirically. As such an evaluation
is based on a limited set of example images, it is unavoidably noisy. Beyond a

However, this is rarely done in medical image segmentation. The width of the

Recent discovery of 20 TeV radiation from the Vela pulsar confirms

Modern approaches for learning on dynamic graphs have adopted the use of

One of the most promising applications in the era of NISQ (Noisy
Intermediate-Scale Quantum) computing is quantum machine learning. Quantum
machine learning offers significant quantum advantages over classical machine
learning across various domains. Specifically, generative adversarial networks
have been recognized fo... | http://arxiv.org/abs/2309.01363v1 |
We present a study of the molecular cloud in Sh2-112 massive star forming
region using the 3-2 transition of CO isotopologues - CO, 13CO, and C18O;
supplemented in part by CGPS HI line emission and MSX data. Sh2-112 is an
optically visible region powered by an O8V type massive star BD +45 3216, and
hosts two Red MSX Su... | http://arxiv.org/abs/2301.02048v1 |
In the context of the Fab-Four theory of gravity in a
Friedmann-Lema\^itre-Robertson-Walker background, in this work we use the
cosmography approach to study a particular self-tuning filter solution focused
on a zero-curvature fixed point to study the $H_0$ tension. In this scheme, the
equations restrict the universe's... | http://arxiv.org/abs/2306.14855v1 |
The MiniBooNE low-energy excess stands as an unexplained anomaly in
short-baseline neutrino oscillation experiments. It has been shown that it can
be explained in the context of dark sector models. Here, we provide an overview
of the possible new-physics solutions based on electron, photon, and dilepton
final states. W... | http://arxiv.org/abs/2308.02543v2 |
We study a class of nonlocal double phase problems with discontinuous
coefficients. A local self-improving property and a higher H\"older continuity
result for weak solutions to such problems are obtained under the assumptions
that the associated coefficient functions are of type VMO (vanishing mean
oscillation) and th... | http://arxiv.org/abs/2303.07749v1 |
Multiview depth imagery will play a critical role in free-viewpoint
television. This technology requires high quality virtual view synthesis to
enable viewers to move freely in a dynamic real world scene. Depth imagery at
different viewpoints is used to synthesize an arbitrary number of novel views.
Usually, depth imag... | http://arxiv.org/abs/2301.11752v1 |
We consider sums of independent identically distributed random variables
whose distributions have $d+1$ atoms. Such distributions never admit an
Edgeworth expansion of order $d$ but we show that for almost all parameters the
Edgeworth expansion of order $d-1$ is valid and the error of the order $d-1$
Edgeworth expansio... | http://arxiv.org/abs/2303.10235v1 |
We study the SAM (Sharpness-Aware Minimization) optimizer which has recently
attracted a lot of interest due to its increased performance over more
classical variants of stochastic gradient descent. Our main contribution is the
derivation of continuous-time models (in the form of SDEs) for SAM and two of
its variants, ... | http://arxiv.org/abs/2301.08203v3 |
It is proved that, for a left hereditary ring, an arbitrary left module has a
representation in the form of the direct sum of a stable left module and
indecomposable projective left modules (if and only if an arbitrary left module
has a representation in the form of the direct sum of a stable left module and
a projecti... | http://arxiv.org/abs/2302.11202v1 |
Quality of Experience~(QoE)-driven adaptive bitrate (ABR) algorithms are
typically optimized using QoE models that are based on the mean opinion
score~(MOS), while such principles may not account for user heterogeneity on
rating scales, resulting in unexpected behaviors. In this paper, we propose
Jade, which leverages ... | http://arxiv.org/abs/2308.04132v2 |
Active visual exploration addresses the issue of limited sensor capabilities
in real-world scenarios, where successive observations are actively chosen
based on the environment. To tackle this problem, we introduce a new technique
called Attention-Map Entropy (AME). It leverages the internal uncertainty of
the transfor... | http://arxiv.org/abs/2303.06457v3 |
We consider the relation between three different approaches to defining
quantum states across several times and locations: the pseudo-density matrix
(PDM), the process matrix, and the multiple-time state approaches. Previous
studies have shown that bipartite two-time states can reproduce the statistics
of bipartite pro... | http://arxiv.org/abs/2306.05958v3 |
The isomorphism between the (extended) BMS$_4$ algebra and the $1+2$D
Carrollian conformal algebra hints towards a co-dimension one formalism of flat
holography with the field theory residing on the null-boundary of the
asymptotically flat space-time enjoying a $1+2$D Carrollian conformal symmetry.
Motivated by this fa... | http://arxiv.org/abs/2304.02696v2 |
