Identifying common backbones of interactions underlying food webs via non-deterministic alignments
Yifan Xu, Carlos Taveras, Lydia Beaudrot +1
The paper presents a scalable, non-deterministic method based on optimal transport to align multiple food‑web networks, revealing common interaction backbones across mammal ecosyst…
Sparse Network Inference under Imperfect Detection and its Application to Ecological Networks
Aoran Zhang, Tianyao Wei, Maria J. Guerrero +1
Recovering latent structure from count data has received considerable attention in network inference, particularly when one seeks both cross-group interactions and within-group sim…
On graphs with finite-time consensus and their use in gradient tracking
Edward Duc Hien Nguyen, Xin Jiang, Bicheng Ying +1
This paper studies sequences of graphs satisfying the finite-time consensus property (i.e., iterating through such a finite sequence is equivalent to performing global or exact ave…
Sparse factorization of the square all-ones matrix of arbitrary order
Xin Jiang, Edward Duc Hien Nguyen, César A. Uribe +1
In this paper, we study sparse factorization of the (scaled) square all-ones matrix of arbitrary order. We introduce the concept of hierarchically banded matrices and propose t…
