On the Fundamental Limits of Matrix Completion: Leveraging Hierarchical Similarity Graphs
Junhyung Ahn, Adel Elmahdy, Soheil Mohajer +1
We study the matrix completion problem that leverages hierarchical similarity graphs as side information in the context of recommender systems. Under a hierarchical stochastic bloc…
Distributed Optimization over Time-varying Graphs with Imperfect Sharing of Information
Hadi Reisizadeh, Behrouz Touri, Soheil Mohajer
We study strongly convex distributed optimization problems where a set of agents are interested in solving a separable optimization problem collaboratively. In this paper, we propo…
When an Energy-Efficient Scheduling is Optimal for Half-Duplex Relay Networks?
Sarthak Jain, Martina Cardone, Soheil Mohajer
This paper considers a diamond network with interconnected relays, namely a network where a source communicates with a destination by hopping information through communicat…
