+- [Reliable uncertainty estimates for neural network predictions](https://nbviewer.jupyter.org/github/krasserm/bayesian-machine-learning/blob/dev/noise-contrastive-priors/ncp.ipynb). 
   Applies noise contrastive priors to Bayesian neural networks to get more reliable uncertainty estimates for OOD data.
   Implemented with Tensorflow 2 and Tensorflow Probability.
