We introduce and study pawn games, a class of two-player zero-sum turn-based
graph games. A turn-based graph game proceeds by placing a token on an initial
vertex, and whoever controls the vertex on which the token is located, chooses
its next location. This leads to a path in the graph, which determines the
winner. Tr... | http://arxiv.org/abs/2305.04096v2 |
Automated audio captioning is multi-modal translation task that aim to
generate textual descriptions for a given audio clip. In this paper we propose
a full Transformer architecture that utilizes Patchout as proposed in [1],
significantly reducing the computational complexity and avoiding overfitting.
The caption gener... | http://arxiv.org/abs/2304.02916v1 |
Photonic moir\'e superlattice as an emerging platform of flatbands can
tightly confine the light inside the cavity and has important applications not
only in linear optics but also in nonlinear optics. In this paper, we
numerically investigate the third- and fifth-order harmonic generation (THG and
FHG) in photonic moi... | http://arxiv.org/abs/2305.03921v1 |
Normalizing Flows are generative models that directly maximize the
likelihood. Previously, the design of normalizing flows was largely constrained
by the need for analytical invertibility. We overcome this constraint by a
training procedure that uses an efficient estimator for the gradient of the
change of variables fo... | http://arxiv.org/abs/2310.16624v2 |
Logic-based approaches to AI have the advantage that their behavior can in
principle be explained with the help of proofs of the computed consequences.
For ontologies based on Description Logic (DL), we have put this advantage into
practice by showing how proofs for consequences derived by DL reasoners can be
computed ... | http://arxiv.org/abs/2308.03705v1 |
Composed image retrieval which combines a reference image and a text modifier
to identify the desired target image is a challenging task, and requires the
model to comprehend both vision and language modalities and their interactions.
Existing approaches focus on holistic multi-modal interaction modeling, and
ignore th... | http://arxiv.org/abs/2310.01358v1 |
Skeleton Ground Truth (GT) is critical to the success of supervised skeleton
extraction methods, especially with the popularity of deep learning techniques.
Furthermore, we see skeleton GTs used not only for training skeleton detectors
with Convolutional Neural Networks (CNN) but also for evaluating
skeleton-related pr... | http://arxiv.org/abs/2310.06437v1 |
The 21-cm power spectrum of reionization is a promising probe for cosmology
and fundamental physics. Exploiting this new observable, however, requires fast
predictors capable of efficiently scanning the very large parameter space of
cosmological and astrophysical uncertainties. In this paper, we introduce the
halo mode... | http://arxiv.org/abs/2302.06626v1 |
We propose a new information transfer protocol for de Sitter space, using
black holes as energy reservoirs. We consider antipodal observers in pure de
Sitter space in the Bunch-Davis state. They can store Hawking modes from the
cosmological horizon in a box. Alternatively, due to thermal fluctuations in de
Sitter space... | http://arxiv.org/abs/2308.13516v1 |
In this paper we consider an entirely new - previously unstudied to the best
of our knowledge - type of density fluctuations stochastic partial differential
equation with a singular coefficient involving the inverse of a probability
density. The equation was recently introduced by Schieber \cite{jay3} while
working on ... | http://arxiv.org/abs/2306.05800v1 |
The main purpose of this work is to report on convincing progress made in the
investigation of the one of the long-standing conceptual problems in QCD,
namely whether the gauge symmetries of the QCD Lagrangian and its ground state
coincide or not? For this purpose, we use only the tensor algebra derivation

Malignant mesothelioma is classified into three histological subtypes,
Epithelioid, Sarcomatoid, and Biphasic according to the relative proportions of
epithelioid and sarcomatoid tumor cells present. Biphasic tumors display
significant populations of both cell types. This subtyping is subjective and
limited by current ... | http://arxiv.org/abs/2302.12653v1 |
