Graphons are important in statistical analysis of network data but existing estimation methods struggle with scalability and resolution-independent approximation.
A novel, scalable graphon estimator using moment matching and implicit neural representations is proposed in this work.
The estimator avoids latent variable modeling and leverages empirical subgraph counts for direct estimation, providing a polynomial-time solution.
The proposed method achieves strong empirical performance, demonstrating high accuracy on small graphs and superior computational efficiency on large graphs compared to existing scalable estimators.
