Assessing the Impact of Contextual Information in Hate Speech Detection
(2023)
Social networks and other digital media deal with huge amounts of user-generated contents
where hate speech has become a problematic more and more relevant. A great effort has been made to
develop automatic tools for its ...
Facet-generating procedures for the maximum-impact coloring polytope
(2023)
Given two graphs G = (V, EG) and H = (V, EH) over the same set of vertices
and given a set of colors C, the impact on H of a coloring c : V → C of G,
denoted I(c), is the number of edges ij ∈ EH such that c(i) = c(j). ...
The presence of irrelevant alternatives paradoxically increases confidence in perceptual decisions
(Cognition, 2023)
Confidence in perceptual decisions is thought to reflect the probability of being correct.
According to this view, confidence should be unaffected or minimally reduced by the
presence of irrelevant alternatives. To test ...
Bone-GAN: Generation of virtual bone microstructure of high resolution peripheral quantitative computed tomography
(Medical PhysicsAmerican Association of Physicists in Medicine, 2023)
Background:Data-driven development of medical biomarkers of bone requires
a large amount of image data but physical measurements are generally too
restricted in size and quality to perform a robust training.
Purpose: ...
NORHA: A NORmal Hippocampal Asymmetry Deviation Index Based on One-Class Novelty Detection and 3D Shape Features
(Brain TopographySpringer, 2023)
Radiologists routinely analyze hippocampal asymmetries in magnetic resonance (MR) images as a biomarker for neurodegenerative conditions like epilepsy and Alzheimer’s Disease. However, current clinical tools rely on either ...
Government Turnover and External Financial Assistance
(Universidad Torcuato Di Tella, 2023)
We study the political incentives shaping governments’ decisions to seek assistance from
a lender of last resort. We propose that re-elected incumbents are more reluctant than newly
elected governments to request assistance, ...
A better alignment between chronotype and school timing is associated with lower grade retention in adolescents
(NPJ Science of Learning, 2023)
Schools start early in the morning all over the world, contrasting with adolescents’ late chronotype. Interestingly, lower academic
performance (i.e. grades or qualifications) was associated with later chronotypes. However, ...
A synthesis of evidence for policy from behavioural science during COVID-19
(Nature ISSN 1476-4687 (online), 2023)
Scientific evidence regularly guides policy decisions1, with behavioural science increasingly part of this process2. In April 2020, an influential paper3 proposed 19 policy recommendations (‘claims’) detailing how evidence ...
Solving the Traveling Salesman Problem with release dates via branch and cut
(EURO Journal on Transportation and Logistics (ISSN 2192-4384)Elsevier, 2023)
In this paper we study the Traveling Salesman Problem with release dates (TSP-rd) and completion time
minimization. The TSP-rd considers a single vehicle and a set of customers that must be served exactly
once with goods ...
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 ...
