Semi-Markov Graph Dynamics [PDF]

open access: yesPLoS ONE, 2011
In this paper, we outline a model of graph (or network) dynamics based on two ingredients. The first ingredient is a Markov chain on the space of possible graphs. The second ingredient is a semi-Markov counting process of renewal type. The model consists in subordinating the Markov chain to the semi-Markov counting process.

Hierarchical graph-based text classification framework with contextual node embedding and BERT-based dynamic fusion

open access: yesJournal of King Saud University: Computer and Information Sciences, 2023
We propose a novel hierarchical graph-based text classification framework that leverages the power of contextual node embedding and BERT-based dynamic fusion to capture the complex relationships between the nodes in the hierarchical graph and generate a ...

Dynamic Balanced Graph Partitioning [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 2020
This paper initiates the study of the classic balanced graph partitioning problem from an online perspective: Given an arbitrary sequence of pairwise communication requests between $n$ nodes, with patterns that may change over time, the objective is to service these requests efficiently by partitioning the nodes into $\ell$ clusters, each of size $k ...

Information spreading in dynamic graphs [PDF]

open access: yesProceedings of the 2012 ACM symposium on Principles of distributed computing, 2012
We present a general approach to study the flooding time (a measure of how fast information spreads) in dynamic graphs (graphs whose topology changes with time according to a random process). We consider arbitrary converging Markovian dynamic graph process, that is, processes in which the topology of the graph at time $t$ depends only on its topology ...

Process Anomaly Detection in Cyber–Physical Production Systems Based on Conditional Discrete-Time Dynamic Graphs

open access: yesApplied Sciences
Various types of anomalies can arise in cyber–physical production systems, caused by either faulty devices or incorrect processes. Anomalies within individual devices can often be detected by applying machine learning techniques to the respective ...
