This is code to run experiments for paper "Self-Supervised Learning for Large-Scale Unsupervised Image Clustering".
For part of the models, you'll need to download the chekpoints manually:
- SimCLR models: https://github.com/google-research/simclr
- MoCo and InfoMin models: https://github.com/HobbitLong/PyContrast/blob/master/pycontrast/docs/MODEL_ZOO.md
- SwAV models: https://github.com/facebookresearch/swav
and put them in chekpoint folder.
For SimCLRv2, BigBiGAN as well as supervised models checkpoints are downloaded automatically.
Remember to clone the submodules by running
git clone --recurse-submodules https://github.com/Randl/kmeans_selfsuper.git
during cloning the repo, or, if you forgot to do it, by running
git submodule update --init --recursive
in the repo folder.
You'll need to install dependencies, by running
pip install -r requirements.txt
For SimCLRv2 and BigBiGAN run
python3 generate_prediction_tf.py --model resnet152_simclr2
python3 generate_prediction_tf.py --model resnet50_simclr2
python3 generate_prediction_tf.py --model resnet152x3_simclr2
python3 generate_prediction_tf.py --model resnet50_bigbigan
python3 generate_prediction_tf.py --model revnet50x4_bigbigan
For InfoMin, MoCo v2 and SwAV, run
python3 generate_prediction_pytorch.py --model resnext152_infomin
python3 generate_prediction_pytorch.py --model resnet50_infomin
python3 generate_prediction_pytorch.py --model resnet50_mocov2
python3 generate_prediction_pytorch.py --model resnet50_swav
Finally, for supervised models, run
python3 generate_prediction_pytorch_supervised.py --model tf_efficientnet_l2_ns_475
python3 generate_prediction_pytorch_supervised.py --model gluon_resnet152_v1s
python3 generate_prediction_pytorch_supervised.py --model ig_resnext101_32x48d
You'll need large amount of RAM since the script keeps features in memory. It was tested on machine with 128 GB RAM.
To run clustering, you need to run
python3 cluster.py --model resnet50_infomin
where the model name should fit the name in generating part. For overclustering, e.g., 1.25 times more clusters than classes, run
python3 cluster.py --model resnet152_simclr2 --over 1.25
For using smaller dimensions of features, e.g., 512, run
python3 cluster.py --model resnet152_simclr2 --n-components 512
