Constrained Diffusion Models with Primal-Dual Inference

Samar Hadou, Yigit Berkay Uslu, Alejandro Ribeiro

This paper develops constrained diffusion models with primal-dual inference (PDI) to sample from optimal distributions of entropy-regularized optimization problems with \emph{avera…

Graph Signal Diffusion Models for Wireless Resource Allocation

Yigit Berkay Uslu, Samar Hadou, Shirin Saeedi Bidokhti +1

We consider constrained ergodic resource optimization in wireless networks with graph-structured interference. We train a diffusion model policy to match expert conditional distrib…

Graph Signal Generative Diffusion Models

Yigit Berkay Uslu, Samar Hadou, Sergio Rozada +2

We introduce U-shaped encoder-decoder graph neural networks (U-GNNs) for stochastic graph signal generation using denoising diffusion processes. The architecture learns node featur…

Generative Diffusion Models for Resource Allocation in Wireless Networks

Yigit Berkay Uslu, Samar Hadou, Shirin Saeedi Bidokhti +1

This paper proposes a supervised training algorithm for learning stochastic resource allocation policies with generative diffusion models (GDMs). We formulate the allocation proble…

Fast State-Augmented Learning for Wireless Resource Allocation with Dual Variable Regression

Yigit Berkay Uslu, Navid NaderiAlizadeh, Mark Eisen +1

We consider resource allocation problems in multi-user wireless networks, where the goal is to optimize a network-wide utility function subject to constraints on the ergodic averag…
