Researchers have introduced a new variational inference framework that extends the utility of tangent approximation to a wider range of probability models, particularly those with strongly super-Gaussian likelihoods. This novel approach utilizes convex duality to create tangent minorants of the log-likelihood, enabling conjugacy with Gaussian priors in otherwise intractable scenarios. The framework offers algorithmic convergence guarantees and near-minimax optimal bounds for variational risk, demonstrating superior performance on simulated and real-world data compared to existing methods.
