extension
branch for more information.This is the official implementation of the E3Outlier framework presented by "Effective End-to-end Unsupervised Outlier Detection via Inlier Priority of Discriminative Network".
The codes are used to reproduce experimental results of E3Outlier and other unsupervised outlier detection (UOD) methods reported in the paper.
To obtain the results of E3Outlier and other UOD methods compared in the paper with default settings, simply run the following command:
python outlier_experiments.py
This will automatically run all UOD methods reported in the manuscript. Please see outlier_experiments.py
for more details.
After training, to print UOD results for a specific algorithm in AUROC/AUPR, run:
# AUROC of E3Outlier on CIFAR10 with outlier ratio 0.1
python evaluate_roc_auc.py --dataset cifar10 --algo_name e3outlier-0.1
# AUPR of CAE-IF on MNIST with outlier ratio 0.25 and inliers as the postive class
python evaluate_pr_auc.py --dataset mnist --algo_name cae-iforest-0.25 --postive inliers
The algorithm names are defined in outlier_experiments.py
.
