Researchers have developed a new framework for Bayesian online learning that preserves fast predictive regret guarantees even with approximate posterior computations. The study demonstrates that the accuracy of the approximate posterior, measured by Wasserstein distance, directly impacts the inherited regret bound. This framework is applied to three examples: linear models using a projected Langevin algorithm, infinite-dimensional exponential family models with prior-preserving truncation, and Gaussian process regression with sparse variational posteriors.
