arXiv:2607.06833v1 Announce Type: new Abstract: Sampling stochastic signals supported on a graph underlies many graph machine learning tasks, including recommender systems, forecasting in financial markets, and wireless network optimization. In these settings, the target signals are realizations of unknown conditional distributions. However, prevailing approaches rely mostly on intricate, application-tailored designs that often regress to a conditional mean instead of sampling from the conditional law. This paper unifies such problems as conditional graph signal generative modeling and tackles
The proliferation of complex networked data in fields like finance and telecommunications, coupled with advancements in generative AI, creates an urgent need for more sophisticated signal modeling approaches compared to traditional regressive methods.
This development allows for more accurate and nuanced simulation and prediction in critical graph-supported systems, moving beyond simple conditional means to full conditional probability distributions.
The ability to sample from true conditional distributions of graph signals will fundamentally improve the realism and fidelity of simulations and predictive models in diverse applications.
