Reducing Per-Sample Interference in Stochastic Optimization
Apostolos Avranas
Modern optimizers combine gradients from the current mini-batch with historical optimization state, such as momentum or adaptive moments. While effective, this standard practice ca…
Towards Disentangling Information Paths with Coded ResNeXt
Apostolos Avranas, Marios Kountouris
The conventional, widely used treatment of deep learning models as black boxes provides limited or no insights into the mechanisms that guide neural network decisions. Significant…
Deep Reinforcement Learning for Resource Constrained Multiclass Scheduling in Wireless Networks
Apostolos Avranas, Marios Kountouris, Philippe Ciblat
The problem of resource constrained scheduling in a dynamic and heterogeneous wireless setting is considered here. In our setup, the available limited bandwidth resources are alloc…
Delay Performance of Multi-Antenna Multicasting in Wireless Networks
Marios Kountouris, Apostolos Avranas
Low-latency communication is currently attracting significant attention due to the emergence of mission-critical Internet of Things (IoT) applications and content-centric services.…
Energy-Latency Tradeoff in Ultra-Reliable Low-Latency Communication with Retransmissions
Apostolos Avranas, Marios Kountouris, Philippe Ciblat
High-fidelity, real-time interactive applications are envisioned with the emergence of the Internet of Things (IoT) and tactile Internet by means of ultra-reliable low-latency comm…
QoS Provisioning in Large Wireless Networks
Marios Kountouris, Nikolaos Pappas, Apostolos Avranas
Quality of service (QoS) provisioning in next-generation mobile communications systems entails a deep understanding of the delay performance. The delay in wireless networks is stro…
Spatial multi-LRU: Distributed Caching for Wireless Networks with Coverage Overlaps
Anastasios Giovanidis, Apostolos Avranas
This article introduces a novel family of decentralised caching policies, applicable to wireless networks with finite storage at the edge-nodes (stations). These policies, that are…
Performance of spatial Multi-LRU caching under traffic with temporal locality
Apostolos Avranas, Anastasios Giovanidis
In this work a novel family of decentralised caching policies for wireless networks is introduced, referred to as spatial multi-LRU. These improve cache-hit probability by exploiti…
Spatial multi-LRU Caching for Wireless Networks with Coverage Overlaps
Anastasios Giovanidis, Apostolos Avranas
This article introduces a novel family of decentralised caching policies, applicable to wireless networks with finite storage at the edge-nodes (stations). These policies are based…
