A single-source shortest path algorithm for dynamic graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Graphs are mathematical structures used in many applications. In recent years, many applications emerged that require the processing of large dynamic graphs where the graph’s structure and properties change constantly over time.

Local Community Detection in Dynamic Graphs Using Personalized Centrality

open access: yesAlgorithms, 2017
Analyzing massive graphs poses challenges due to the vast amount of data available. Extracting smaller relevant subgraphs allows for further visualization and analysis that would otherwise be too computationally intensive.

Cops and Robbers on Dynamic Graphs: Offline and Online Case [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
We examine the classic game of Cops and Robbers played on models of dynamic graphs, that is, graphs evolving over discrete time steps. At each time step, a graph instance is generated as a subgraph of the underlying graph of the model.

Representation Learning for Dynamic Functional Connectivities via Variational Dynamic Graph Latent Variable Models

open access: yesEntropy, 2022
Latent variable models (LVMs) for neural population spikes have revealed informative low-dimensional dynamics about the neural data and have become powerful tools for analyzing and interpreting neural activity.

Objets connectés et mobilité urbaine : visualiser les déplacements des usagers de Twitter avec des graphes dynamiques

open access: yesM@ppemonde, 2020
With the digital turn, data from connected devices are a new resource for understanding urban rhythms and mobility. Using the geolocated messages (1, 540, 000 tweets) of Twitter social network users recorded in 2015, this article uses dynamic graphs to ...

The Evaluation of DyHATR Performance for Dynamic Heterogeneous Graphs

open access: yesJournal of ICT Research and Applications, 2023
Dynamic heterogeneous graphs can represent real-world networks. Predicting links in these graphs is more complicated than in static graphs. Until now, research interest of link prediction has focused on static heterogeneous graphs or dynamically ...

Cover Time in Edge-Uniform Stochastically-Evolving Graphs

open access: yesAlgorithms, 2018
We define a general model of stochastically-evolving graphs, namely the edge-uniform stochastically-evolving graphs. In this model, each possible edge of an underlying general static graph evolves independently being either alive or dead at each discrete

Static Call Graph Combination to Simulate Dynamic Call Graph Behavior

open access: yesIEEE Access, 2022
Call graphs are fundamental for many higher-level code analyses. The selection of the most appropriate call graph construction tool for an analysis is not always straightforward and depends on the purpose of the results’ further usage.

Dynamic FastMap: An Efficient Algorithm for Spatiotemporal Embedding of Dynamic Graphs

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference, 2023
Efficiently embedding graphs in a Euclidean space has many benefits: It allows us to interpret and solve graph-theoretic problems using geometric and analytical methods.

Motion sensing superpixels (MOSES) is a systematic computational framework to quantify and discover cellular motion phenotypes

open access: yeseLife, 2019
Correct cell/cell interactions and motion dynamics are fundamental in tissue homeostasis, and defects in these cellular processes cause diseases. Therefore, there is strong interest in identifying factors, including drug candidates that affect cell/cell ...
