A review of dynamic network models with latent variables

B Kim, KH Lee, L Xue, X Niu - Statistics surveys, 2018‏ - pmc.ncbi.nlm.nih.gov
We present a selective review of statistical modeling of dynamic networks. We focus on
models with latent variables, specifically, the latent space models and the latent class …

Network interdependencies and the evolution of the international arms trade

PW Thurner, CS Schmid, SJ Cranmer… - Journal of Conflict …, 2019‏ - journals.sagepub.com
Since few states are able to produce all of their own military hardware, a majority of
countries' military systems rely on weapon imports. The structure of the international defense …

Networks of cooperation: Rebel alliances in fragmented civil wars

EK Gade, M Gabbay, MM Hafez… - Journal of Conflict …, 2019‏ - journals.sagepub.com
When rebels make alliances, what informs their choice of allies? Civil wars are rarely simple
contests between rebels and incumbent regimes. Rather, rival militant networks provide the …

Fratricide in rebel movements: A network analysis of Syrian militant infighting

EK Gade, MM Hafez, M Gabbay - Journal of Peace …, 2019‏ - journals.sagepub.com
Violent conflict among rebels is a common feature of civil wars and insurgencies. Yet, not all
rebel groups are equally prone to such infighting. While previous research has focused on …

Diffusion across international organizations: Connectivity and convergence

T Sommerer, J Tallberg - International Organization, 2019‏ - cambridge.org
While extensive research shows that policies and institutions spread across states through
processes of diffusion, we know little about diffusion among international organizations …

Inferential approaches for network analysis: AMEN for latent factor models

S Minhas, PD Hoff, MD Ward - Political Analysis, 2019‏ - cambridge.org
We introduce a Bayesian approach to conduct inferential analyses on dyadic data while
accounting for interdependencies between observations through a set of additive and …

Path coherence and disruption in routine dynamics

I Kim, BT Pentland, KA Frank… - Organization Science, 2024‏ - pubsonline.informs.org
We use evidence from a disruption of clinical documentation routines to propose a novel,
predictive mechanism for routine dynamics based on path coherence. Path coherence refers …

The ALCORE Tensor Decomposition for Sparse Count Data

J Hood, AJ Schein - International Conference on Artificial …, 2024‏ - proceedings.mlr.press
This paper introduces AL $\ell_0 $ CORE, a new form of probabilistic non-negative tensor

Networks of violence: Predicting conflict in Nigeria

C Dorff, M Gallop, S Minhas - The Journal of Politics, 2020‏ - journals.uchicago.edu
Civil conflicts are complex: multiple warring parties compete for control of territory both
against each other and the government. These processes are often dynamic, changing over …

Change point estimation in a dynamic stochastic block model

M Bhattacharjee, M Banerjee, G Michailidis - Journal of machine learning …, 2020‏ - jmlr.org
We consider the problem of estimating the location of a single change point in a network
