Although neural networks are powerful function approximators, the underlying modelling assumptions ultimately define the likelihood and thus the hypothesis class they are parameterizing.

In this paper, we question this assumption and show that proper Bayesian inference with function space priors induced by neural networks does not necessarily lead to good OOD detection.

The need to avoid confident predictions on unfamiliar data has sparked interest in out-of-distribution (OOD) detection.

We offer a practical deep learning implementation of our framework based on probabilistic task-conditioned hypernetworks, an approach we term posterior meta-replay.

The largely successful method of training neural networks is to learn their weights using some variant of stochastic gradient descent (SGD).
