This repository presents the experiments of the paper:
Posterior Network: Uncertainty Estimation without OOD Samples via Density-Based Pseudo-Counts
Bertrand Charpentier, Daniel Zügner, Stephan Günnemann
Conference on Neural Information Processing Systems (NeurIPS), 2020.
To install requirements:
conda env create -f environment.yaml
conda activate posterior-network
conda env list
To train the model(s) in the paper, run one jupyter notebook in the folder notebooks. All parameter are described.
To dowload the datasets, follow the following links:
- 2DGaussians vs anomalous2D
- Segment (No sky) vs Segment (Sky only)
- SensorlessDrive (No 10, 11) vs SensorlessDrive (10, 11 only)
- MNIST vs FashionMNIST / KMNIST
- CIFAR10 vs SVHN
You can find pre-trained models in the folder saved_models.
