• Abstract: Artificial intelligence (AI) has been introduced in communication networks and services to improve efficiency via self-optimization. Cooperative intelligence (CI), also known as collective intelligence and collaborative intelligence, is expected to become an integral element in next-generation networks because it can aggregate the capabilities and intelligence of multiple devices. However, privacy issues may intimidate, obstruct, and hinder the deployment of CI in practice because collaboration heavily relies on data and information sharing. Additional practical constraints in communication (e.g., limited bandwidth) further limit the performance of CI. To overcome these challenges, we propose PP-MARL, an efficient privacy-preserving learning scheme based on multi-agent reinforcement learning (MARL). We apply and evaluate our scheme in two communication-related use cases: mobility management in drone-assisted communication and network control with edge intelligence. Simulation results reveal that the proposed scheme can achieve efficient and reliable collaboration with 1.1-6 times better privacy protection and lower overheads (e.g., 84-91% reduction in bandwidth) than state-of-the-art approaches.

  LLM-based Multi-Agent Systems (MAS) have proven highly effective in solving complex problems by integrating multiple agents, each performing different roles. In this paper, we introduce the concept of Federated MAS, highlighting the fundamental differences between Federated MAS and traditional FL. We then identify key challenges in developing Federated MAS, including: 1) heterogeneous privacy protocols among agents, 2) structural differences in multi-party conversations, and 3) dynamic conversational network structures. To address these challenges, we propose Embedded Privacy-Enhancing Agents (EPEAgent), an innovative solution that integrates seamlessly into the Retrieval-Augmented Generation phase and the

  One of the main challenges in offline Reinforcement Learning (RL) is the distribution shift that arises from the learned policy deviating from the data collection policy. This is often addressed by avoiding out-of-distribution (OOD) actions during policy improvement as their presence can lead to substantial performance degradation. We introduce AlberDICE, an offline MARL algorithm that performs centralized training of individual agents based on stationary distribution optimization.
