Message from the Chairs of the WAIN workshop 2021

We are pleased towelcome you to the 3rd InternationalWorkshop on AI in Networks and Distributed Systems (WAIN). The workshop aims to present high-quality researches leveraging machine learning and data analysis solutions to take full advantage of network systems and infrastructures. In detail, this year WAIN presents innovations for data center scheduling and management and network monitoring and security, using, among the others, node embedding techniques, GNN and federated learning. This year, our technical program is rich and varied, with 1 keynote speech and 6 accepted papers thoroughly evaluated and selected by the 18 members of the Technical Program Committee. All papers received at least 3 reviews, and decisions were made after a vigorous online discussion. In an effort to increase the technical soundness of the contributions, we have increased the papers page limit to 5 pages plus references. For the second year, and hopefully the last one, the workshop is entirely virtual with live streaming presentations to encourage researchers to interact, share their experiences and ideas and discuss the open issues. We would like to thank both the Authors and the Technical Program Committee for their hard work and precious contribution for making WAIN a fruitful workshop.
