question by examining the influence of neighbors' innovativeness and the
structure of the innovators' network on a sector's capacity to develop new
technologies. We study these two dimensions of technological interdependence by
applying novel met... | http://arxiv.org/abs/2308.00014v3 |
The flow network model is an established approach to approximate
pressure-flow relationships in a bifurcating network, and has been widely used
in many contexts. Existing models typically assume unidirectional flow and
exploit Poiseuille's law, and thus neglect the impact of bifurcation geometry
and finite-sized object... | http://arxiv.org/abs/2309.11230v2 |
With the introduction of ChatGPT, OpenAI made large language models (LLM)
accessible to users with limited IT expertise. However, users with no
background in natural language processing (NLP) might lack a proper
understanding of LLMs. Thus the awareness of their inherent limitations, and
therefore will take the systems... | http://arxiv.org/abs/2310.03031v3 |
Graphs are a widely used data structure for collecting and analyzing
relational data. However, when the graph structure is distributed across
several parties, its analysis is particularly challenging. In particular, due
to the sensitivity of the data each party might want to keep their partial
knowledge of the graph pr... | http://arxiv.org/abs/2309.10890v1 |
Large-scale pre-training has made progress in many fields of natural language
processing, though little is understood about the design of pre-training
datasets. We propose a methodology for obtaining a quantitative understanding
of structural overlap between machine translation tasks. We apply our
methodology to the na... | http://arxiv.org/abs/2307.16795v1 |
The internal structure of doped holes in the Mott insulator may provide
important insight into the physics of doped cuprates. Its observability via a
single-particle probe by scanning tunneling spectroscopy (STS) and
angle-resolved photo-emission spectroscopy (ARPES) is explored in this paper.
Specifically we study the... | http://arxiv.org/abs/2309.11556v2 |
This paper proposes a new active learning method for semantic segmentation.
The core of our method lies in a new annotation query design. It samples
informative local image regions (e.g., superpixels), and for each of such
regions, asks an oracle for a multi-hot vector indicating all classes existing
in the region. Thi... | http://arxiv.org/abs/2309.09319v2 |
We develop models to classify desirable reasoning revisions in argumentative
writing. We explore two approaches -- multi-task learning and transfer learning
-- to take advantage of auxiliary sources of revision data for similar tasks.
Results of intrinsic and extrinsic evaluations show that both approaches can
indeed i... | http://arxiv.org/abs/2309.07334v1 |
We discuss the base 3/2 representation of the natural numbers. We prove that
the sum of digits function of the representation is a fixed point of a 2-block
substitution on an infinite alphabet, and that this implies that sum of digits
function modulo 2 of the representation is a fixed point $x_{3/2}$ of a 2-block
subst... | http://arxiv.org/abs/2301.13563v1 |
A recently released Temporal Graph Benchmark is analyzed in the context of
Dynamic Link Property Prediction. We outline our observations and propose a
trivial optimization-free baseline of "recently popular nodes" outperforming
other methods on medium and large-size datasets in the Temporal Graph
Benchmark. We propose ... | http://arxiv.org/abs/2309.15730v3 |
The Higgs-gluon interaction is crucial for LHC phenomenology. To improve the
constraints on the CP structure of this coupling, we investigate Higgs
production with two jets using machine learning. In particular, we exploit the
CP sensitivity of the so far neglected phase space region that differs from the
typical vecto... | http://arxiv.org/abs/2309.03146v1 |
Mechanical proofs by logical relations often involve tedious reasoning about
substitution. In this paper, we show that this is not necessarily the case, by
developing, in Agda, a proof that all simply typed lambda calculus expressions
evaluate to values. A formalization of the proof is remarkably short (~40 lines
of co... | http://arxiv.org/abs/2309.15724v1 |
