This paper explores methods for extracting information from radiology reports
that generalize across exam modalities to reduce requirements for annotated
data. We demonstrate that multi-pass T5-based text-to-text generative models
exhibit better generalization across exam modalities compared to approaches
that employ B... | http://arxiv.org/abs/2306.09544v1 |
Security Application Programming Interfaces (APIs) are crucial for ensuring
software security. However, their misuse introduces vulnerabilities,
potentially leading to severe data breaches and substantial financial loss.
Complex API design, inadequate documentation, and insufficient security
training often lead to unin... | http://arxiv.org/abs/2306.08869v2 |
Simulations of neutrino interactions are playing an increasingly important
role in the pursuit of high-priority measurements for the field of particle
physics. A significant technical barrier for efficient development of these
simulations is the lack of a standard data format for representing individual
neutrino scatte... | http://arxiv.org/abs/2310.13211v2 |
On-device Deep Neural Network (DNN) inference consumes significant computing
resources and development efforts. To alleviate that, we propose LUT-NN, the
first system to empower inference by table lookup, to reduce inference cost.
LUT-NN learns the typical features for each operator, named centroid, and
precompute the ... | http://arxiv.org/abs/2302.03213v2 |
We consider the three-dimensional incompressible Euler equations on a bounded
domain $\Omega$ with $C^3$ boundary. We prove that if the velocity field $u \in
C^{0,\alpha} (\Omega)$ with $\alpha > 0$ (where we are omitting the time
dependence), it follows that the pressure $p \in C^{0, \alpha} (\Omega)$. In
order to pro... | http://arxiv.org/abs/2304.01952v1 |
Dietary assessment is essential to maintaining a healthy lifestyle. Automatic
image-based dietary assessment is a growing field of research due to the
increasing prevalence of image capturing devices (e.g. mobile phones). In this
work, we estimate food energy from a single monocular image, a difficult task
due to the l... | http://arxiv.org/abs/2309.00468v3 |
Adversarial attacks insert small, imperceptible perturbations to input
samples that cause large, undesired changes to the output of deep learning
models. Despite extensive research on generating adversarial attacks and
building defense systems, there has been limited research on understanding
adversarial attacks from a... | http://arxiv.org/abs/2301.12896v3 |
An inner-product Hilbert space formulation of the Kemeny distance is defined
over the domain of all permutations with ties upon the extended real line, and
results in an unbiased minimum variance (Gauss-Markov) correlation estimator
upon a homogeneous i.i.d. sample. In this work, we construct and prove the
necessary re... | http://arxiv.org/abs/2305.00965v1 |
The purpose of this paper is mostly to present conjectures that extend, to
the ``triangular partition'' context (partitions ``under any line'' in the
terminology of Blaziak-Haiman-Morse-Pun-Seelinger), properties of Frobenius of
multivariate diagonal harmonics modules | http://arxiv.org/abs/2303.02224v1 |
Embodiment has recently enjoyed renewed consideration as a means to amplify
the faculties of smart machines. Proponents of embodiment seem to imply that
optimizing for movement in physical space promotes something more than the
acquisition of niche capabilities for solving problems in physical space.
However, there is ... | http://arxiv.org/abs/2307.08598v1 |
Composed image retrieval (CIR) is the task of retrieving specific images by
using a query that involves both a reference image and a relative caption. Most
existing CIR models adopt the late-fusion strategy to combine visual and
language features. Besides, several approaches have also been suggested to
generate a pseud... | http://arxiv.org/abs/2310.05473v1 |
Sparse matrix-vector multiplication (SpMV) is an essential linear algebra
operation that dominates the computing cost in many scientific applications.
Due to providing massive parallelism and high memory bandwidth, GPUs are
commonly used to accelerate SpMV kernels. Prior studies mainly focused on
reducing the latency o... | http://arxiv.org/abs/2302.05662v1 |
Following the UK Government's Living with COVID-19 Strategy and the end of
universal testing, hospital admissions are an increasingly important measure of
COVID-19 pandemic pressure. Understanding leading indicators of admissions at
National Health Service (NHS) Trust, regional and national geographies help
