Generate FedFR Dataset

You can follow the steps in split_dataset to generate our pretrained, and FL dataset.

Prerequisite

  1. Put the pretrained model ("backbone.pth") under the pretrain/ folder.

Training our FedFR

  1. In config.py, you should first change the path of config.rec and config.local_rec
  2. Run with command sh run.sh.
  3. After training, you will have models saved in the checkpoint directory, eg., ckpt/FedFR/.

Generic Evaluation

You will evaluate the generic performance on IJBC dataset.

You can use ijbc_conti.py to continuously evaluate all checkpoints saved in the directory. (eg. epoch 5 to epoch 11)

python3 ijbc_conti.py --root_path PATH/TO/IJBC/ --ckpt_dir ckpt/FedFR --epoch 5 6 7 8 9 10 11 \
        --gpu 0 1 2 3 --job 'both'

There are two types of job, '1:1' and '1:n', as described in our paper. If you want to evaluate both, you can use --job 'both'.

Personalized Evaluation

Each model trained by client before FedAvg model aggregation will be used to evaluate the personalized performance.

Furthermore, as described in paper, the backbone and the tranformation layer will be concatenated to generate personalized features.

The evaluation scripts are as follows:

We only provide single checkpoint for some epoch and single type of evaluation ('1:1' or '1:n')

1:1 Evaluation

python3 local_all.py --backbone 'multi' --task '1:1' --ckpt_path ckpt/FedFR \
                     --data_dir $VERI_DIR --gallery $GALLERY_DIR --epoch 11 --num_client 40 --gpu 0 1 2 3
  • $VERI_DIR is the path to 'local_veri_4000' when you split your dataset, eg. '/home/jackieliu/face_recognition/ms1m_split/local_veri_4000'
  • $GALLERY_DIR is the path to 'local_gallery_4000', eg. '/home/jackieliu/face_recognition/ms1m_split/local_gallery_4000'

1:n Evaluation

python3 local_all.py --backbone 'multi' --task '1:n' --ckpt_path ckpt/FedFR \
                     --data_dir $VERI_DIR --gallery $GALLERY_DIR --epoch 11 --num_client 40 --gpu 0 1 2 3
  • $VERI_DIR is the path to 'local_veri_4000' when you split your dataset, eg. '/home/jackieliu/face_recognition/ms1m_split/local_veri_4000'
  • $GALLERY_DIR is the path to 'local_gallery_4000', eg. '/home/jackieliu/face_recognition/ms1m_split/local_gallery_4000'
