Learning Sparse Graphs via Majorization-Minimization for Smooth Node Signals

no code implementations6 Feb 2022 Ghania Fatima, Aakash Arora, Prabhu Babu, Petre Stoica

The proposed algorithm does not require tuning of any hyperparameter and it has the desirable feature of eliminating the inactive variables in the course of the iterations - which can help speeding up the algorithm.

PDMM: A novel Primal-Dual Majorization-Minimization algorithm for Poisson Phase-Retrieval problem

no code implementations16 Oct 2021 Ghania Fatima, Zongyu Li, Aakash Arora, Prabhu Babu

In this paper, we introduce a novel iterative algorithm for the problem of phase-retrieval where the measurements consist of only the magnitude of linear function of the unknown signal, and the noise in the measurements follow Poisson distribution.
