Amortized Bayesian model comparison with evidential deep learning

1 code implementation22 Apr 2020

This makes the method particularly effective in scenarios where model fit needs to be assessed for a large number of datasets, so that per-dataset inference is practically infeasible. Finally, we propose a novel way to measure epistemic uncertainty in model comparison problems.
