Adversarial Water-Filling: Theory, Algorithms, and a Domain-Specific Wireless Foundation Model

Read the original on arXiv Machine Learning →

The paper introduces the adversarial water-filling (AWF) framework for competitive resource allocation in frequency and space, particularly targeting multi-operator low Earth orbit satellite spectrum sharing. It presents theoretical results, algorithms, and a domain‑specific wireless foundation model that uses permutation‑invariant channel representations, a constraint‑aware graph neural network, and learned projected extragradient iterations to approximate stationary solutions of the minimax problem. Experiments show the model generalizes to unseen problem sizes and achieves over an order‑of‑magnitude speedup compared to Mirror‑Prox while maintaining comparable solution quality.

Differentiable Policy Transport over Multi-Layer Network Feasibility Geometry

The paper introduces Network Feasibility Geometry Reinforcement Learning (NFG‑RL), a method that enforces multi‑layer network constraints—such as interference, power‑rate coupling, flow conservation, service chains, capacity, latency, and reliability—by transporting a proto‑policy through a differentiable feasibility map. By compiling heterogeneous constraints into typed residual blocks and using a variational transport operator, NFG‑RL ensures almost‑sure feasible execution and shapes exploration and gradients to respect active constraints. Experiments on two wireless‑edge surrogate environments show that NFG‑RL boosts feasible utility by 37.5–41.5 %, cuts raw‑action violations by 48.5–60.8 %, and reduces P99 delay by 57.0–75.5 % compared to leading baselines.
