Greening AI Inference with Accuracy and Latency-aware User Incentives
Vasilios A. Siris, Adamantia Stamou, George D. Stamoulis +2
The widespread use of AI services has raised concerns for its environmental sustainability, towards which recent studies have identified carbon emissions of AI inference as the maj…
The Cost of Relaxation: Evaluating the Error in Convex Neural Network Verification
Merkouris Papamichail, Konstantinos Varsos, Giorgos Flouris +1
Many neural network (NN) verification systems represent the network's input-output relation as a constraint program. Sound and complete, representations involve integer constraints…
Incentivising green video streaming through a 2-tier subscription model with carbon-aware rewards
Vasilios A. Siris, Adamantia Stamou, George D. Stamoulis +1
We investigate incentives for reducing the carbon emissions of video streaming that depend on the energy consumption of segments in the end-to-end video delivery path, the carbon i…
User Acceptance Model for Smart Incentives in Sustainable Video Streaming towards 6G
Konstantinos Varsos, Adamantia Stamou, George D. Stamoulis +1
The rapid growth of 5G video streaming is intensifying energy consumption across access, core, and data-center networks, underscoring the critical need for energy and carbon-effici…
Optimal Energy-Aware Service Management in Future Networks with a Gamified Incentives Mechanism
Konstantinos Varsos, Adamantia Stamou, George D. Stamoulis +1
As energy demands surge across ICT infrastructures, service providers must engage users in sustainable practices while maintaining the Quality of Experience (QoE) at acceptable lev…
Adaptation Procedure in Misinformation Games
Konstantinos Varsos, Merkouris Papamichail, Giorgos Flouris +1
We study interactions between agents in multi-agent systems, in which the agents are misinformed with regards to the game that they play, essentially having a subjective and incorr…
Revisit the Arimoto-Blahut algorithm: New Analysis with Approximation
Michail Fasoulakis, Konstantinos Varsos, Apostolos Traganitis
By the seminal paper of Claude Shannon \cite{Shannon48}, the computation of the capacity of a discrete memoryless channel has been considered as one of the most important and funda…
Noisy Games: A Study on the Effect of Noise on Game Specifications
Constantinos Varsos, Giorgos Flouris, Marina Bitsaki
We consider misinformation games, i.e., multi-agent interactions where the players are misinformed with regards to the game that they play, essentially having an \emph{incorrect} u…
Forward Looking Best-Response Multiplicative Weights Update Methods for Bilinear Zero-sum Games
Michail Fasoulakis, Evangelos Markakis, Yannis Pantazis +1
Our work focuses on extra gradient learning algorithms for finding Nash equilibria in bilinear zero-sum games. The proposed method, which can be formally considered as a variant of…
