Estimating Sequences with Memory for Minimizing Convex Non-smooth Composite Functions
Endrit Dosti, Sergiy A. Vorobyov, Themistoklis Charalambous
First-order optimization methods are crucial for solving large-scale data processing problems, particularly those involving convex non-smooth composite objectives. For such problem…
A New Class of Composite Objective Multi-step Estimating-sequence Techniques (COMET)
Endrit Dosti, Sergiy A. Vorobyov, Themistoklis Charalambous
We devise a new accelerated gradient-based estimating sequence technique for solving large-scale optimization problems with composite structure. More specifically, we introduce a n…
Effective Energy Efficiency of Ultra-reliable Low Latency Communication
Mohammad Shehab, Hirley Alves, Eduard A. Jorswieck +2
Effective Capacity defines the maximum communication rate subject to a specific delay constraint, while effective energy efficiency (EEE) indicates the ratio between effective capa…
Embedding a Heavy-Ball type of Momentum into the Estimating Sequences
Endrit Dosti, Sergiy A. Vorobyov, Themistoklis Charalambous
We present a new accelerated gradient-based method for solving smooth unconstrained optimization problems. The goal is to embed a heavy-ball type of momentum into the Fast Gradient…
Ultra Reliable Communication via Optimum Power Allocation for HARQ Retransmission Schemes
Endrit Dosti, Mohammad Shehab, Hirley Alves +1
In this work, we develop low complexity, optimal power allocation algorithms that would allow ultra reliable operation at any outage probability target with minimum power consumpti…
Power Allocation for Type-I ARQ Two-Hop Cooperative Networks for Ultra-Reliable Communication
Endrit Dosti, Themistoklis Charalambous, Risto Wichman
We analyze the performance of amplify-and-forward (AF) automatic repeat request (ARQ) for a two-hop cooperative system with reliability constrains. For this setup, we first derive…
