Marginal Likelihood Gradient for Bayesian Neural Networks

no code implementations pproximateinference AABI Symposium 2021 Marcin B. Tomczak, Richard E Turner

Bayesian learning of neural networks is attractive as it can protecting against over-fitting and provide automatic methods for inferring important hyperparameters by maximizing the marginal probability of the data.

Variational Inference

Compatible features for Monotonic Policy Improvement

no code implementations9 Oct 2019 Marcin B. Tomczak, Sergio Valcarcel Macua, Enrique Munoz de Cote, Peter Vrancx

In this work we establish conditions under which the parametric approximation of the critic does not introduce bias to the updates of surrogate objective.

Policy Optimization Through Approximate Importance Sampling

1 code implementation9 Oct 2019 Marcin B. Tomczak, Dongho Kim, Peter Vrancx, Kee-Eung Kim

These proxy objectives allow stable and low variance policy learning, but require small policy updates to ensure that the proxy objective remains an accurate approximation of the target policy value.
