Official PyTorch Repository of "Difficulty-Aware Simulator for Open Set Recognition" (ECCV 2022 Paper)

1. Requirements

• python 3.6+
• torch 1.2+
• torchvision 0.4+
• CUDA 10.1+
• scikit-learn 0.22+

Split information & Dataset

Split information for all datasets can be found in split.py.

splits_F1 and splits_AUROC are split information for each benchmark with F1 score and AUROC.

When you run the code, datasets except tiny-ImageNet will be automatically downloaded.

[Tiny_ImageNet Download Link]

2. Training & Evaluation

python osr.py --dataset 'cifar10'

To run the code, execute osr.py. Then, the results will be saved under the "logs" directory.

sh osr.sh

For simplicity, we provide the training scripts for running all datasets. You can execute the shell file by the above command.

++ Since [Open-Set Recognition: a Good Closed-Set Classifier is All You Need?] elaborated additional techniques with searched hyperparameters can boost OSR performances, we here simply conduct and compare the performances of DIAS and ARPL+cs.
