Bayesian topology inference on partially known networks from input-output pairs

M Sevilla, S Segarra - ICASSP 2024-2024 IEEE International …, 2024 - ieeexplore.ieee.org
We propose a sampling algorithm to perform system identification from a set of input-output
graph signal pairs. The dynamics of the systems we study are given by a partially known …

Learning Cartesian Product Graphs with Laplacian Constraints

C Shi, G Mishne - International Conference on Artificial …, 2024 - proceedings.mlr.press
Graph Laplacian learning, also known as network topology inference, is a problem of great
interest to multiple communities. In Gaussian graphical models (GM), graph learning …

Learning signals and graphs from time-series graph data with few causes

P Misiakos, V Mihal, M Püschel - ICASSP 2024-2024 IEEE …, 2024 - ieeexplore.ieee.org
In this paper we port assumptions and techniques from DAG (directed acyclic graph)
learning and causal inference to time-series graph data. In particular, we view such data as …

Learning Multiplex Graph With Inter-Layer Coupling

C Zhang, HT Wai - ICASSP 2024-2024 IEEE International …, 2024 - ieeexplore.ieee.org
In many real-life systems, the interactions among entities are complex and varied. This
necessitates the use of a multiplex graph model with heterogeneous layers of graphs to …
