We develop variational Laplace for Bayesian neural networks (BNNs) which exploits a local approximation of the curvature of the likelihood to estimate the ELBO without the need for stochastic sampling of the neural-network weights.

Variational inference in Bayesian neural networks is usually performed using stochastic sampling which gives very high-variance gradients, and hence slow learning.
