SDE Net (Keras)

This repo contains the code for the paper:

Lingkai Kong, Jimeng Sun and Chao Zhang, SDE-Net: Equipping Deep Neural Network with Uncertainty Estimates, ICML2020.

[paper] [video]

Package installation

virtualenv -p python3 venv && source venv/bin/activate # optional but recommended.
pip install -r requirements.txt && pip install -e . # install the package.

Training & Evaluation

Supported datasets are: MNIST, SVHN, CIFAR10, CIFAR100. Supported models are RESNET and SDENET.

Look at the bash run scripts at the root of the repository to get started for training and evaluation.

Comparison between official Pytorch implementation and Keras

This comparison is just the result of one run. No runs were handpicked. Overall it's very similar.

Except probably SDENET on SVHN (95% vs 94%).
