Towards Unsupervised Deep Graph Structure Learning

Yixin Liu et al.

Summary: This paper discusses the success and limitations of graph neural networks (GNNs) in graph-related applications, and proposes a more practical unsupervised graph structure learning paradigm that optimizes the graph topology through self-supervised contrastive learning.

A Tactical Conflict Resolution Proposal for U-Space Zu Airspace Volumes

Jesus Jover et al.

Summary: This paper presents a prediction-based conflict-free adaptive navigation technique called PCAN, which modifies the velocity vector of UAVs to avoid conflicts effectively. Performance evaluation demonstrates its superiority in high-density scenarios, with low overhead in flight time or distance traveled by UAVs to reach their destinations.

Emergence of 4-D System Fundamental Diagram in Urban Air Mobility Traffic Flow

Christopher Cummings et al.

Summary: The study investigates traffic flow and congestion development in urban air mobility (UAM), using a non-linear program to provide more flexible detour options. Results show that UAM traffic flows mimic those of other modes, highlighting the importance of carefully managing airspace capacity for optimal system performance.
