A polyhedral study of a relaxation of the routing and spectrum allocation problem
(Procedia Computer ScienceElsevier, 2023)
The routing and spectrum allocation (RSA) problem arises in the context of flexible grid optical networks, and consists in routing
a set of demands through a network while simultaneously assigning a bandwidth to each ...
Multiobjective formulation for last-mile optimization in wireless networks
(IEEE2023 XLIX Latin American Computer Conference (CLEI), 2023)
Internet of Things (IoT) is a technology that serves as the basis for smart environments. The ever-expanding set of applications that provide intelligence in different scenarios is continually growing and expanding. From ...
Demand Estimation under Uncertain Consideration Sets
(Operations Research (ISSN: 0030-364X), 2023-09)
To estimate customer demand, choice models rely both on what the individuals do and do not purchase. A customer may not purchase a product because it was not offered but also because it was not considered. To account for ...
Predicción de la satisfacción del usuario a partir de chats de atención al cliente
(Memorias de las JAIIO, 2023)
Los servicios de atención al cliente son determinantes de la experiencia de usuario de las empresas Fintech. Este trabajo busca entender, empleando técnicas de machine learning, qué factores llevan a ...
VesselVAE: Recursive Variational Autoencoders for 3D Blood Vessel Synthesis
(Universidad Torcuato Di Tella, 2023)
We present a data-driven generative framework for synthesizing blood vessel 3D geometry. This is a challenging task due to the
complexity of vascular systems, which are highly variating in shape, size,
and structure. ...
Learning normal asymmetry representations for homologous brain structures
(Universidad Torcuato Di Tella, 2023)
Although normal homologous brain structures are approximately symmetrical by definition, they also have shape differences due
to e.g. natural ageing. On the other hand, neurodegenerative conditions
induce their own changes ...
Teamwork Quality Prediction Using Speech-Based Features
(SMM23, Workshop on Speech, Music and Mind 2023, 2023)
This paper describes a novel protocol for annotating teamwork quality and related variables, based only on the speech signal. Our protocol was designed to annotate a Spanish version of the Objects Games corpus, a publicly ...
A Value-Based Well-Being Framework
(Journal of MacromarketingSAGE, 2023)
This article presents and illustrates a novel value-based well-being framework, derived from service-dominant logic notions of the
link between value and well-being. Based in a wide range of disciplines, this framework ...
The wisdom of extremized crowds: Promoting erroneous divergent opinions increases collective accuracy
(Universidad Torcuato Di Tella, 2023)
The aggregation of many lay judgements can generate surprisingly accurate estimates. This effect, known
as the “wisdom of the crowd”, has been demonstrated in domains such as medical decision-making, factchecking
news, ...
A branch-and-cut algorithm for the routing and spectrum allocation problem
(Universidad Torcuato Di Tella, 2023)
One of the most promising solutions to deal with huge data traffic demands in
large communication networks is given by flexible optical networking, in particular
the flexible grid (flexgrid) technology specified in the ...
