Benchmark Datasets

1. FederatedEMNIST (default)

   Download from this [link] and place them in your data directory data_dir.

   python src/main.py --dataset FederatedEMNIST --model CNN -A 10 -K 3400 --lr_local 0.1 -B 20 -R 2000 

2. CelebA

   Download from the original CelebA homepage [link].

   python src/main.py --dataset CelebA --model CNN -A 10 -K 9343 --lr_local 0.005 -B 5 -R 100

3. FederatedCIFAR100

   Download from this [link].

    python src/main.py --dataset FedCIFAR100 --model ResNet -A 10 -K 500 --lr_local 0.1 -B 20 -R 4000 

4. FederatedCIFAR10 (Partitioned by Dirichlet distribution, followed by Clustered Sampling)

   Don't need to download any dataset.

    python src/main.py --dataset PartitionedCIFAR10 --model CNN -A 10 -K 100 --lr_local 0.001 -B 50 -R 1000 

5. Reddit

    python src/main.py --dataset Reddit --model BLSTM -A 200 -K 7527 --maxlen 400 \
        --alpha1 0.75 --alpha2 0.01 --alpha3 0.1 \
        --lr_local 0.01 --lr_global 0.001 -E 2 -B 128 -R 100
