Yizhe Zhu, Mohamed Elhoseiny, Bingchen Liu, Xi Peng and Ahmed Elgammal "A Generative Adversarial Approach for Zero-Shot Learning from Noisy Texts", CVPR, 2018

Data: You can download the dataset CUBird and NABird
Put the uncompressed data to the folder "data"

python train_CUB.py --splitmode easy
python train_CUB.py --splitmode hard

python train_NAB.py --splitmode easy
python train_NAB.py --splitmode hard

Download the data and compress it to the folder 'data/GBU'.

python train_GBU.py --dataset CUB1 --preprocessing --z_dim 100
python train_GBU.py --dataset AWA1 --preprocessing --z_dim 10
python train_GBU.py --dataset AWA2 --preprocessing --z_dim 10
python train_GBU.py --dataset APY --preprocessing --z_dim 10
python train_GBU.py --dataset SUN --preprocessing --z_dim 10
python train_GBU.py --dataset FLO --preprocessing --z_dim 100
