This repository is the official implementation of Detecting Errors and Estimating Accuracy on Unlabeled Data with Self-training Ensembles.

• It is tested under Ubuntu Linux 16.04.1 and Python 3.6 environment, and requires some packages to be installed: PyTorch, numpy and scikit-learn.
• To install requirements: pip install -r requirements.txt

• MNIST-M: download it from the Google drive. Extract the files and place them in ./dataset/mnist_m/.
• SVHN: need to download Format 2 data (*.mat). Place the files in ./dataset/svhn/.
• USPS: download the usps.h5 file. Place the file in ./dataset/usps/.

• train_model.py: train standard models via supervised learning.
• train_dann.py: train domain adaptive (DANN) models.
• eval_pipeline.py: evaluate various methods on all tasks.

• To train a standard model via supervised learning, you can use the following command:

python train_model.py --source-dataset {source dataset} --model-type {model type} --base-dir {directory to save the model}

{source dataset} can be mnist, mnist-m, svhn or usps.

{model type} can be typical_dnn or dann_arch.

• To train a domain adaptive (DANN) model, you can use the following command:

python train_dann.py --source-dataset {source dataset} --target-dataset {target dataset} --base-dir {directory to save the model} [--test-time]

{source dataset} (or {target dataset}) can be mnist, mnist-m, svhn or usps.

The argument --test-time is to indicate whether to replace the target training dataset with the target test dataset.

• To evaluate a method on all training-test dataset pairs, you can use the following command:

python eval_pipeline.py --model-type {model type} --method {method}

{model type} can be typical_dnn or dann_arch.

{method} can be conf_avg, ensemble_conf_avg, conf, trust_score, proxy_risk, our_ri or our_rm.

You can run the following scrips to pre-train all models needed for the experiments.

• run_all_model_training.sh: train all supervised learning models.
• run_all_dann_training.sh: train all DANN models.
• run_all_ensemble_training.sh: train all ensemble models.

You can run the following script to get the results reported in the paper.

• run_all_evaluation.sh: evaluate all methods on all tasks.

We provide pre-trained models produced by our training scripts: run_all_model_training.sh, run_all_dann_training.sh and run_all_ensemble_training.sh.

You can download the pre-trained models from Google Drive.

Part of this code is inspired by estimating-generalization and TrustScore.
