The Game is the Game: Dynamic network analysis and shifting roles in criminal networks
Daniel Catlin, Giulia Berlusconi, David J. B. Lloyd
Objectives: This paper incorporates time as a crucial variable to identify key players in criminal networks and explores how actors' positions change over time. It then assesses th…
Influence network reconstruction from discrete time-series of count data modelled by multidimensional Hawkes processes
Naratip Santitissadeekorn, Martin Short, David J. B. Lloyd
Identifying key influencers from time series data without a known prior network structure is a challenging problem in various applications, from crime analysis to social media. Whi…
Tracking and forecasting oscillatory data streams using Koopman autoencoders and Kalman filtering
Stephen A Falconer, David J. B. Lloyd, Naratip Santitissadeekorn
Data-driven modelling techniques provide a method for deriving models of dynamical systems directly from complicated data streams. However, tracking and forecasting such data strea…
Identification of an influence network using ensemble-based filtering for Hawkes processes driven by count data
Santitissadeekorn N., Delahaies S., Lloyd D. J. B
Many networks have event-driven dynamics (such as communication, social media and criminal networks), where the mean rate of the events occurring at a node in the network changes a…
