Alpha-VI DeepONet: A prior-robust variational Bayesian approach for enhancing DeepONets with uncertainty quantification

Soban Nasir Lone, Subhayan De, Rajdip Nayek

We introduce a novel deep operator network (DeepONet) framework that incorporates generalised variational inference (GVI) using Rényi's $\hat{I}\pm$-divergence to learn complex operators…
