currently experience. Base... | http://arxiv.org/abs/2306.11041v1 |
In this paper a martingale problem for super-Brownian motion with interactive
branching is derived. The uniqueness of the solution to the martingale problem
is obtained by using the pathwise uniqueness of the solution to a corresponding
system of SPDEs with proper boundary conditions. The existence of the solution
to t... | http://arxiv.org/abs/2303.05832v1 |
Training Artificial Intelligence (AI) models on 3D images presents unique
challenges compared to the 2D case: Firstly, the demand for computational
resources is significantly higher, and secondly, the availability of large
datasets for pre-training is often limited, impeding training success. This
study proposes a simp... | http://arxiv.org/abs/2307.06614v3 |
Neutrino experiments in a Forward Physics Facility at the Large Hadron
Collider can measure neutrino and antineutrino cross sections for energies up
to a few TeV. For neutrino energies below 100 GeV, the inelastic cross section
evaluations have contributions from weak structure functions at low momentum
transfers and l... | http://arxiv.org/abs/2307.09241v2 |
We study the potential of the Quantum Chromodynamics axion in hot and/or
dense quark matter, within a Nambu-Jona-Lasinio-like model that includes the
coupling of the axion to quarks. Differently from previous studies, we
implement local electrical neutrality and $\beta-$equilibrium, which are
relevant for the descripti... | http://arxiv.org/abs/2304.10240v1 |
Search query classification, as an effective way to understand user intents,
is of great importance in real-world online ads systems. To ensure a lower
latency, a shallow model (e.g. FastText) is widely used for efficient online
inference. However, the representation ability of the FastText model is
insufficient, resul... | http://arxiv.org/abs/2308.01098v3 |
We have witnessed the rapid proliferation of multimodal data on numerous
social media platforms. Conventional studies typically require massive labeled
data to train models for Multimodal Aspect-Based Sentiment Analysis (MABSA).
However, collecting and annotating fine-grained multimodal data for MABSA is
tough. To alle... | http://arxiv.org/abs/2305.10169v2 |
Self-supervised learning (SSL) is a popular paradigm for representation
learning. Recent multiview methods can be classified as sample-contrastive,
dimension-contrastive, or asymmetric network-based, with each family having its
own approach to avoiding informational collapse. While these families converge
to solutions ... | http://arxiv.org/abs/2310.02903v4 |
Thanks to the rapid growth in wearable technologies and recent advancement in
machine learning and signal processing, monitoring complex human contexts
becomes feasible, paving the way to develop human-in-the-loop IoT systems that
naturally evolve to adapt to the human and environment state autonomously.
Nevertheless, ... | http://arxiv.org/abs/2303.04292v2 |
We present a series of algorithms for skein manipulation in a genus-2
handlebody, implementing a novel strand sorting method to reduce any skein to a
skein in a 2-punctured disk. This reduction guarantees resolution as a linear
combination of basis elements of the Kauffman Bracket Skein Module. Manually,
these skein ma... | http://arxiv.org/abs/2305.18535v1 |
Slot attention is a powerful method for object-centric modeling in images and
videos. However, its set-equivariance limits its ability to handle videos with
a dynamic number of objects because it cannot break ties. To overcome this
limitation, we first establish a connection between slot attention and optimal
transport... | http://arxiv.org/abs/2301.13197v2 |
In October 2019, Nature published a paper [6] describing an experimental work
that was performed at Google. The paper claims to demonstrate quantum
(computational) supremacy on a 53-qubit quantum computer. Since then we have
been involved in a long-term project to study various statistical aspects of
the Google experim... | http://arxiv.org/abs/2305.01064v1 |
We investigate the challenge of parametrizing policies for reinforcement
learning (RL) in high-dimensional continuous action spaces. Our objective is to
develop a multimodal policy that overcomes limitations inherent in the
commonly-used Gaussian parameterization. To achieve this, we propose a
principled framework that... | http://arxiv.org/abs/2307.10710v1 |
