Constituency parsing plays a fundamental role in advancing natural language
processing (NLP) tasks. However, training an automatic syntactic analysis
system for ancient languages solely relying on annotated parse data is a
formidable task due to the inherent challenges in building treebanks for such
languages. It deman... | http://arxiv.org/abs/2308.04645v2 |
For the purpose of inspecting power plants, autonomous robots can be built
using reinforcement learning techniques. The method replicates the environment
and employs a simple reinforcement learning (RL) algorithm. This strategy might
be applied in several sectors, including the electricity generation sector. A
pre-trai... | http://arxiv.org/abs/2303.09013v1 |
We study how to transfer representations pretrained on source tasks to target
tasks in visual percept based RL. We analyze two popular approaches: freezing
or finetuning the pretrained representations. Empirical studies on a set of
popular tasks reveal several properties of pretrained representations. First,
finetuning... | http://arxiv.org/abs/2302.06009v1 |
We construct and develop a similitude version of exceptional theta
correspondences and show that the Howe duality theorem follows from that for
the "isometry" case. We also extend basic tools such as the seesaw identity
associated to seesaw dual pairs to the similitude setting. | http://arxiv.org/abs/2308.13339v1 |
We proposed a general quantum-computing-based algorithm that harnesses the
exponential power of noisy intermediate-scale quantum (NISQ) devices in solving
partial differential equations (PDE). This variational quantum eigensolver
(VQE)-inspired approach transcends previous idealized model demonstrations
constrained by ... | http://arxiv.org/abs/2310.11764v2 |
As general purpose vision models get increasingly effective at a wide set of
tasks, it is imperative that they be consistent across the tasks they support.
Inconsistent AI models are considered brittle and untrustworthy by human users
and are more challenging to incorporate into larger systems that take
dependencies on... | http://arxiv.org/abs/2303.16133v2 |
In recent years, there has been a surging demand for edge computing of image
processing and machine learning workloads. This has reignited interest in the
development of custom hardware accelerators that can deliver enhanced
performance and improved energy efficiency. These workloads frequently
demonstrate affine memor... | http://arxiv.org/abs/2309.03203v1 |
Color Doppler echocardiography is a widely used non-invasive imaging modality
that provides real-time information about the intracardiac blood flow. In an
apical long-axis view of the left ventricle, color Doppler is subject to phase
wrapping, or aliasing, especially during cardiac filling and ejection. When
setting up... | http://arxiv.org/abs/2306.13695v2 |
Ensuring adequate ventilation of exterior and interior urban spaces is
essential for the safety and comfort of inhabitants. Here, we examine how
angled features can steer wind into areas with stagnant air, promoting natural
ventilation. Using Large Eddy Simulations (LES) and wind tunnel experiments
with particle image ... | http://arxiv.org/abs/2310.01577v2 |
We study the problem of optimal sampling in an edge-based video analytics
system (VAS), where sensor samples collected at a terminal device are offloaded
to a back-end server that processes them and generates feedback for a user.
Sampling the system with the maximum allowed frequency results in the timely
detection of ... | http://arxiv.org/abs/2302.00478v2 |
We consider an $XYZ$ spin chain within the framework of the generalized
algebraic Bethe ansatz. We study form factors of local operators corresponding
to the singlet states in the limit of free fermions. We obtain explicit
representations for these form factors. | http://arxiv.org/abs/2308.15748v2 |
