Positional Attention-based Graph Neural Network for Learning Permutation Non-equivariant Wireless Policies

Baichuan Zhao, Chenyang Yang, Jianyu Zhao +1

The paper introduces a positional attention‑based graph neural network that can learn wireless policies which are not permutation equivariant, improving channel estimation and end‑…
