A graph-based ranked-list model for unsupervised distance learning on shape retrieval
(2016-11-01)
Several re-ranking algorithms have been proposed recently. Some effective approaches are based on complex graph-based diffusion processes, which usually are time consuming and therefore inappropriate for real-world large ...
RaDE: A rank-based graph embedding approach
(2020-01-01)
Due to possibility of capturing complex relationships existing between nodes, many application benefit of being modeled with graphs. However, performance issues can be observed on large scale networks, making it computationally ...
RaDE: A Rank-based Graph Embedding Approach
(Scitepress, 2020-01-01)
Due to possibility of capturing complex relationships existing between nodes, many application benefit of being modeled with graphs. However, performance issues can be observed on large scale networks, making it computationally ...
Asymptotic optimality of degree-greedy discovering of independent sets in Configuration Model graphs
(Elsevier Science, 2021-01)
Finding independent sets of maximum size in fixed graphs is well known to be an NP-hard task. Using scaling limits, we characterise the asymptotics of sequential degree-greedy explorations and provide sufficient conditions ...
Halting the isolation of jaguars: Where to act locally to sustain connectivity in their southernmost population
(Wiley Blackwell Publishing, Inc, 2017-05)
Habitat loss and fragmentation are among the major threats to the conservation of biodiversity. Improvement of landscape connectivity becomes one of the main strategies for alleviating these threats and is an increasingly ...
GraFa: Scalable faceted browsing for RDF graphs
(Springer Verlag, 2018)
Faceted browsing has become a popular paradigm for user interfaces on the Web and has also been investigated in the context of RDF graphs. However, current faceted browsers for RDF graphs encounter performance issues when ...
A Graph-based Ranked-list Model For Unsupervised Distance Learning On Shape Retrieval
(Elsevier Science BVAmsterdam, 2016)
GENE: Graph generation conditioned on named entities for polarity and controversy detection in social media
(ELSEVIER SCI LTD, 2020)
Many of the interactions between users on social networks are controversial, specially in polarized environments. In effect, rather than producing a space for deliberation, these environments foster the emergence of users ...
Mineração de padrões de correlação estrutural em grandes grafos
(Universidade Federal de Minas GeraisUFMG, 2011-05-05)
Graphs have been established as a powerful theoretical framework for modeling several types of interactions in a variety of scenarios. While the availability of large scale data led to the development of aframework for ...
Scale-invariant transition probabilities in free word association trajectories
(Frontiers Research Foundation, 2009-09)
Free-word association has been used as a vehicle to understand the organization of human thoughts. The original studies relied mainly on qualitative assertions, yielding the widely intuitive notion that trajectories ...
