Quasi Black-Box Variational Inference with Natural Gradients for Bayesian Learning

no code implementations23 May 2022 Martin Magris, Mostafa Shabani, Alexandros Iosifidis

Our Quasi Black-box Variational Inference (QBVI) framework is readily applicable to a wide class of Bayesian inference problems and is of simple implementation as the updates of the variational posterior do not involve gradients with respect to the model parameters, nor the prescription of the Fisher information matrix.
