Usage

For traning with the cascaded multihead structure on different datasets:

python cascade_CIFAR-10.py --bits '4' --gpu '1' --batch-size 64
python cascade_FLICKR.py --bits '4' --gpu '1' --batch-size 64
python cascade_NUS_WIDE.py --bits '4' --gpu '1' --batch-size 64

For traning with the flat multihead structure on different datasets:

python flat_CIFAR-10.py --bits '4' --gpu '1' --batch-size 64
python flat_FLICKR.py --bits '4' --gpu '1' --batch-size 64
python flat_NUS_WIDE.py --bits '4' --gpu '1' --batch-size 64
