    Point2Radio: A Foundation Model for Cross-Scene Radio Fields from Material-Aware Point Clouds

    Chaozheng Wen, Chenghong Bian, Hongze Chen, Jun Zhang

    cs.NI · cs.AI · cs.CV · cs.LG

    High-fidelity radio fields are typically simulated for every scene--transmitter configuration or fitted separately to each scene, failing to exploit propagation structures shared across environments. We present Point2Radio, a foundation model that learns a transferable propagation prior from multiple environments. Given a material-aware point cloud and a transmitter (TX) setting, a common encoder produces a TX-conditioned scene representation...

    When Unlearning Fails: Reliable Data Deletion under Post-Training in Agent Networks

    Zihao Ding, Jun Huang, Liang Dong

    cs.NI · cs.LG

    Self-improving federated agent networks keep training after deployment by collecting new trajectories with the current policy and feeding them back into later rounds. This closed loop makes unlearning harder than a one-time model repair. When a data owner requests deletion, the target data may have already shaped later retained trajectories, so retraining or model-side unlearning can leave an influence echo that returns as the network...
