Recently, large language models (LLMs), including notable models such as
GPT-4 and burgeoning community models, have showcased significant general
language understanding abilities. However, there has been a scarcity of
attempts to assess the logical reasoning capacities of these LLMs, an essential
facet of natural lang... | http://arxiv.org/abs/2310.09107v1 |
Abstraction-based techniques are an attractive approach for synthesizing
correct-by-construction controllers to satisfy high-level temporal
requirements. A main bottleneck for successful application of these techniques
is the memory requirement, both during controller synthesis and in controller
deployment.
We propos... | http://arxiv.org/abs/2307.03783v1 |
Pre-trained large language models (LLMs) have recently achieved better
generalization and sample efficiency in autonomous web automation. However, the
performance on real-world websites has still suffered from (1) open domainness,
(2) limited context length, and (3) lack of inductive bias on HTML. We
introduce WebAgent... | http://arxiv.org/abs/2307.12856v4 |
Human demonstrations of trajectories are an important source of training data
for many machine learning problems. However, the difficulty of collecting human
demonstration data for complex tasks makes learning efficient representations
of those trajectories challenging. For many problems, such as for dexterous
manipula... | http://arxiv.org/abs/2310.16027v2 |
This study proposes a tractable stochastic choice model to identify
motivations for prosocial behavior, and to explore alternative motivations of
deliberate randomization beyond ex-ante fairness concerns. To represent social
preferences, we employ an additively perturbed utility model consisting of the
sum of expected ... | http://arxiv.org/abs/2304.14977v1 |
This article introduces VARAHA, an open-source, fast, non-Markovian sampler
for estimating gravitational-wave posteriors. VARAHA differs from existing
Nested sampling algorithms by gradually discarding regions of low likelihood,
rather than gradually sampling regions of high likelihood. This alternative
mindset enables... | http://arxiv.org/abs/2303.01463v2 |
Anthropogenic greenhouse gases have been changing significantly the climate
and causing dire effects on the dynamics of the Earth System. We examine the
conditions under which the well of a geostationary orbital lift can be used to
dump greenhouse gases into space. | http://arxiv.org/abs/2307.13590v2 |
We explore long-term temporal visual correspondence-based optimization for 3D
video object detection in this work. Visual correspondence refers to one-to-one
mappings for pixels across multiple images. Correspondence-based optimization
is the cornerstone for 3D scene reconstruction but is less studied in 3D video
objec... | http://arxiv.org/abs/2303.15416v1 |
Stochastic variational inference and its derivatives in the form of
variational autoencoders enjoy the ability to perform Bayesian inference on
large datasets in an efficient manner. However, performing inference with a VAE
requires a certain design choice (i.e. reparameterization trick) to allow
unbiased and low varia... | http://arxiv.org/abs/2308.08053v1 |
On the basis of relationship between the kinetic equation for two soliton
clouds in the theory of the Korteweg-de Vries equation and equations of the
Chaplygin gas dynamics it is shown that the existence of waves propagating
without a change in their form is a fundamental property of the nonlinear
dynamics of soliton g... | http://arxiv.org/abs/2301.04362v1 |
This paper describes SPINDLE - an open source Python module implementing an
efficient and accurate parser for written Dutch that transforms raw text input
to programs for meaning composition, expressed as {\lambda} terms. The parser
integrates a number of breakthrough advances made in recent years. Its output
consists ... | http://arxiv.org/abs/2302.12050v1 |
Being around for decades, the problem of Authorship Attribution is still very
much in focus currently. Some of the more recent instruments used are the
pre-trained language models, the most prevalent being BERT. Here we used such a
model to detect the authorship of texts written in the Romanian language. The
dataset us... | http://arxiv.org/abs/2301.12500v1 |
Background: Software security is crucial to ensure that the users are
protected from undesirable consequences such as malware attacks which can
result in loss of data and, subsequently, financial loss. Technical Debt (TD)
is a metaphor incurred by suboptimal decisions resulting in long-term
consequences such as increas... | http://arxiv.org/abs/2307.11387v1 |
