To design and deploy artificial intelligence (AI)-enabled sixth-generation (6G) zero-touch automated wireless networks, scalability, trust and explainability of AI algorithms are required. Recent advances in standardization point out fully decentralized AI as the way to deploy large-scale network automation. In ETSI's zero-touch architecture—for instance—each network domain is endowed with a data collection element that feeds a local AI analytics and decision entity. The central entity plays only the role of a coordinator/model aggregator without necessarily having access to the distributed raw data. Nonetheless automatically managing a massive number of network elements by only increasing the processing resources is not a guarantee for scalability since it also increases the complexity of their management, the degree of contention in the system, as well as suffers from the lack of collaboration between the distributed decision entities. A scalable architecture would therefore achieve a trade-off in i) utilization of shared resources to minimize contention but also to avoid complex management of unnecessary resources; ii) information flow by sharing only compressed parameters instead of raw data and iii) degree of collaboration by enabling the exchange of inferences between decentralized analytics/decision engines while avoiding that they fall in competitive or too cooperative situations.
On the other hand, the practical deployment of AI automation in 6G requires establishing a high level of trust and transparency in the AI black boxes. In this regard, explainable AI (XAI) tools and metrics will play a pivotal role in unveiling the rationale behind AI predictions and decisions. From the state-of-the-art gradient-based attribution methods—such as Integrated Gradients, Saliency Maps and ε-LRP—to perturbation-based attribution methods such as Shapley Value sampling, the XAI framework enables a better understanding of the causality in AI models.
