Periodic Reporting for period 2 - VERGE (AI-powered eVolution towards opEn and secuRe edGe architEctures)

Okres sprawozdawczy: 2024-01-01 do 2025-06-30

Podsumowanie kontekstu i ogólnych celów projektu

The main goal of VERGE has been to provide an integrated approach on how to tackle the challenges of edge computing evolution described around three main pillars: (1)“Edge for AI (Edge4AI)”, namely a flexible, modular and converged edge platform design, unifying the Life Cycle Management (LCM) and closed-loop automation for cloud-native applications, Multi-access Edge Computing (MEC) and network services across a multi-domain edge-cloud continuum, while fully exploiting the capabilities of cutting-edge multi-core and multi-accelerator platforms for ultra-high computational performance. (2) “AI for edge (AI4Edge)” namely an AI-powered portfolio of solutions that will leverage the multitude of information and metrics provided by the VERGE platform monitoring mechanisms to manage and orchestrate the VERGE platform computing and network resources. (3) “Security, privacy and trustworthiness for AI (SPT4AI)”, through a suite of methods and tools that will ensure a) security of the AI-based models against adversarial attacks, b) privacy of data and models, and c) sample-efficient training, safety verification and explainability for model decisions, resulting in improved trust in AI models.
This main goal has been achieved through the following specific obejctives:
1.- Design an open and secure edge computing architecture to efficiently support highly demanding XR and IoT-driven applications in terms of computation and connectivity, relying on an edge-cloud continuum that fosters virtualisation of massive heterogeneous edge computing resources across a multi-access RAN.
2.-Design and build the Edge4AI concept that provides the infrastructure, mechanisms and programming tools to enable the development, deployment and orchestration of massively distributed AI processes across heterogeneous computing and memory resources.
3.-Design an AI4Edge framework that encompasses cutting-edge AI solutions for managing and orchestrating the edge computing and the RAN resources towards an optimum performance that satisfies the highly demanding applications requiring extremely low latencies and/or very high-capacity justifying edge processing and computing.
4.-Develop tools that ensure the security, privacy and trustworthiness of the VERGE system.
5. Showcase the VERGE solutions by means of Proof of Concept (PoC) demonstrations.
6. Carry out extensive dissemination, standardisation and exploitation activities.

The project solutions have impacted on different improvement areas, namely reduced latency, enhanced service availability, enhanced service reliability, efficient resource utilization, energy efficiency, flexibility/scalability, enhanced computation, efficient AI model training, AI safety and AI explainability.
