Learning Sparse Graphs via Majorization-Minimization for Smooth Node Signals
Ghania Fatima, Aakash Arora, Prabhu Babu +1
In this letter, we propose an algorithm for learning a sparse weighted graph by estimating its adjacency matrix under the assumption that the observed signals vary smoothly over th…
