Deep networks tend to learn spurious feature-label correlations in real-world
supervised learning tasks. This vulnerability is aggravated in distillation,
where a student model may have lesser representational capacity than the
corresponding teacher model. Often, knowledge of specific spurious correlations
is used to r... | http://arxiv.org/abs/2310.18590v2 |
This paper proposes an efficient and effective method for joint gaze location
detection (GL-D) and gaze object detection (GO-D), \emph{i.e.}, gaze following
detection. Current approaches frame GL-D and GO-D as two separate tasks,
employing a multi-stage framework where human head crops must first be detected
and then b... | http://arxiv.org/abs/2308.13857v1 |
Named Entity Recognition (NER) is a fundamental NLP tasks with a wide range
of practical applications. The performance of state-of-the-art NER methods
depends on high quality manually anotated datasets which still do not exist for
some languages. In this work we aim to remedy this situation in Slovak by
introducing Wik... | http://arxiv.org/abs/2304.04026v1 |
This paper presents a model to simulate behavior of particle-laden slurry in
a horizontal perforated wellbore with the goal of quantifying fluid and
particle distribution between the perforations. There are two primary phenomena
that influence the result. The first one is the non-uniform particle
distribution within th... | http://arxiv.org/abs/2301.10855v1 |
Image-to-image reconstruction problems with free or inexpensive metadata in
the form of class labels appear often in biological and medical image domains.
Existing text-guided or style-transfer image-to-image approaches do not
translate to datasets where additional information is provided as discrete
classes. We introd... | http://arxiv.org/abs/2303.08863v2 |
We study close-packed dimers on the quasiperiodic Ammann-Beenker (AB) graph,
that was recently shown to have the unusual feature that hard-core dimer
constraints are exactly reproduced at successive discrete length scales. This
observation led to a conjecture that it would be possible to construct an exact
real-space d... | http://arxiv.org/abs/2302.07879v1 |
Existing learning-based methods for point cloud rendering adopt various 3D
representations and feature querying mechanisms to alleviate the sparsity
problem of point clouds. However, artifacts still appear in rendered images,
due to the challenges in extracting continuous and discriminative 3D features
from point cloud... | http://arxiv.org/abs/2303.16485v1 |
This paper addresses the problem of distributed optimization, where a network
of agents represented as a directed graph (digraph) aims to collaboratively
minimize the sum of their individual cost functions. Existing approaches for
distributed optimization over digraphs, such as Push-Pull, require agents to
exchange exp... | http://arxiv.org/abs/2305.15202v2 |
Cellular Vehicle-to-Everything (C-V2X) is a frontier in the evolution of
distributed communication introduced in 3GPP release 14 to advanced use cases.
While research efforts continue to optimize the accessible bandwidth for
transportation ecosystem, a bottom up analysis from the application layer
perspective is necess... | http://arxiv.org/abs/2303.06696v1 |
Generative diffusion models, including Stable Diffusion and Midjourney, can
generate visually appealing, diverse, and high-resolution images for various
applications. These models are trained on billions of internet-sourced images,
raising significant concerns about the potential unauthorized use of

Understanding the light ring, one kind fundamental orbit, shall provide us
with novel insight into the astronomical phenomena, such as the ringdown of
binary merger and shadow of black holes. Recently, topological approach has
preliminarily demonstrated its potential advantages on the properties of the
light rings. How... | http://arxiv.org/abs/2307.14003v1 |
The multiple-valued quantum logic is formulated systematically such that the
truth values are represented naturally as unique roots of unity placed on the
unit circle. Consequently, multi-valued quantum neuron (MVQN) is based on the
principles of multiple-valued threshold logic over the field of complex
numbers. The tr... | http://arxiv.org/abs/2305.02018v5 |
Recent progress has been made in understanding optimisation dynamics in
neural networks trained with full-batch gradient descent with momentum with the
uncovering of the edge of stability phenomenon in supervised learning. The edge
of stability phenomenon occurs as the leading eigenvalue of the Hessian reaches
the dive... | http://arxiv.org/abs/2307.04210v1 |
The Reeb space of a continuous function is the space of connected components
of the level sets. In this paper we characterize those smooth functions on
closed manifolds whose Reeb spaces have the structure of a finite graph. We
also give several explicit examples of smooth functions on closed manifolds
such that they t... | http://arxiv.org/abs/2308.05953v1 |
