DeepAL+ is a extended toolkit originated from DeepAL toolkit. Including python implementations of the following active learning algorithms:

• Random Sampling
• Least Confidence [1]
• Margin Sampling [2]
• Entropy Sampling [3]
• Uncertainty Sampling with Dropout Estimation [4]
• Bayesian Active Learning Disagreement [4]
• Core-Set Selection [5]
• Adversarial margin [6]
• Mean Standard Deviation [7]
• Variation Ratios [8]
• Cost-Effective Active Learning [9]
• KMeans with scikit-learn library and with faiss-gpu library
• Batch Active learning by Diverse Gradient Embeddings [10]
• Loss Prediction Active Learning [11]
• Variational Adversarial Active Learning [12]
• Wasserstein Adversarial Active Learning [13]

We support 10 datasets, MNIST, FashionMNIST, EMNIST, SVHN, CIFAR10, CIFAR100, Tiny ImageNet, BreakHis, PneumoniaMNIST, Waterbirds. One can add new dataset by adding new function get_newdataset() in data.py.

Tiny ImageNet, BreakHis, PneumoniaMNIST need to be download manually, the corresponding data addresses could be found in data.py.

In DeepAL+, we use ResNet18 as basic classifier. One can replace it to other basic classifiers and add them to nets.py.

• numpy 1.21.2
• scipy 1.7.1
• pytorch 1.10.0
• torchvision 0.11.1
• scikit-learn 1.0.1
• tqdm 4.62.3
• ipdb 0.13.9
• openml 0.12.2
• faiss-gpu 1.7.2
• toma 1.1.0
• opencv-python 4.5.5.64
• wilds 2.0.0 (for waterbirds dataset only)

You can also use the following command to install conda environment

conda env create -f environment.yml

faiss-gpu and wilds should use pip install.

  python demo.py \
      -a RandomSampling \
      -s 100 \
      -q 1000 \
      -b 100 \
      -d MNIST \
      --seed 4666 \
      -t 3 \
      -g 0

See arguments.py for more instructions. We have also construct a comparative survey based on DeepAL+. Please refer here for more details.
