low-power... | http://arxiv.org/abs/2302.07328v1 |
Differentially private SGD (DP-SGD) holds the promise of enabling the safe
and responsible application of machine learning to sensitive datasets. However,
DP-SGD only provides a biased, noisy estimate of a mini-batch gradient. This
renders optimisation steps less effective and limits model utility as a result.
With thi... | http://arxiv.org/abs/2308.12018v1 |
Aims. In astronomy, machine learning has been successful in various tasks
such as source localisation, classification, anomaly detection, and
segmentation. However, feature regression remains an area with room for
improvement. We aim to design a network that can accurately estimate sources'
features and their uncertain... | http://arxiv.org/abs/2305.14495v2 |
This paper introduces SAMAug, a novel visual point augmentation method for
the Segment Anything Model (SAM) that enhances interactive image segmentation
performance. SAMAug generates augmented point prompts to provide more
information about the user's intention to SAM. Starting with an initial point
prompt, SAM produce... | http://arxiv.org/abs/2307.01187v4 |
Chip-based optical frequency combs address the demand for compact, bright,
coherent light sources of equidistant phase-locked lines. Traditionally, the
Fourier Transform Spectroscopy (FTS) technique has been considered a suboptimal
choice for resolving comb lines in chip-based sensing applications due to the
requiremen... | http://arxiv.org/abs/2303.13074v1 |
Machine learning has shown significant breakthroughs in quantum science,
where in particular deep neural networks exhibited remarkable power in modeling
quantum many-body systems. Here, we explore how the capacity of data-driven
deep neural networks in learning the dynamics of physical observables is
correlated with th... | http://arxiv.org/abs/2302.04621v2 |
The quantum nature of light enables potentially revolutionary communication
technologies. Key to advancing this area of research is a clear understanding
of the concepts of states, modes, fields, and photons. The concept of field
modes carries over from classical optics, while the concept of state has to be
considered ... | http://arxiv.org/abs/2306.07807v1 |
We introduce InFusionSurf, an innovative enhancement for neural radiance
field (NeRF) frameworks in 3D surface reconstruction using RGB-D video frames.
Building upon previous methods that have employed feature encoding to improve
optimization speed, we further improve the reconstruction quality with minimal
impact on o... | http://arxiv.org/abs/2303.04508v3 |
In this paper, we present an iterative algorithm that detects and estimates
the specular components and estimates the diffuse component of
single-input-multiple-output (SIMO) ultra-wide-band (UWB) multipath channels.
Specifically, the algorithm super-resolves the specular components in the
delay-angle-of-arrival domain... | http://arxiv.org/abs/2308.01702v3 |
This work revisits quantum algorithms for the well-known welded tree problem,
proposing a very succinct quantum algorithm based on the simplest coined
quantum walks. It simply iterates the naturally defined coined quantum walk
operator for a predetermined time and finally measure, where the predetermined
time can be ef... | http://arxiv.org/abs/2304.08395v2 |
Fine-tuning is widely used as the default algorithm for transfer learning
from pre-trained models. Parameter inefficiency can however arise when, during
transfer learning, all the parameters of a large pre-trained model need to be
updated for individual downstream tasks. As the number of parameters grows,
fine-tuning i... | http://arxiv.org/abs/2303.03267v1 |
While Chain-of-Thought prompting is popular in reasoning tasks, its
application to Large Language Models (LLMs) in Natural Language Understanding
(NLU) is under-explored. Motivated by multi-step reasoning of LLMs, we propose
Coarse-to-Fine Chain-of-Thought (CoF-CoT) approach that breaks down NLU tasks
into multiple rea... | http://arxiv.org/abs/2310.14623v1 |
Superconducting stiffness $\rho_s$ and coherence length $\xi$ are usually
determined by measuring the penetration depth $\lambda$ of a magnetic field and
the upper critical field $H_{c2}$ of a superconductor (SC), respectively.
However, in magnetic SC, e.g. some of the iron-based, this could lead to
erroneous results s... | http://arxiv.org/abs/2305.01926v1 |
