GDAN

Code for the paper "Generative Dual Adversarial Network for Generalized Zero-shot Learning"

Dataset is available here, please download and extract it under ./data and make sure the "data_root" variable in config yaml file is correct.

Dependencies

• Python 3.6, PyTroch 0.4
• sklearn, scipy, numpy, tqdm

Steps to run the program

1. Modify config files as needed.

2. Pretrain CVAE, and checkpoints are stored in the directory specified by "vae_dir" in config file:

   python pretrain_gdan.py --config configs/cub.yml

3. Choose which CVAE checkpoint you want to use to initialize the GDAN model and modify the "vae_ckpt" variable in the yaml file. Then we can train GDAN by running:

   python train_gdan.py --config configs/cub.yml

4. Use validation data to decide which saved checkpoint of GDAN (directory specified by "ckpt_dir" in config yaml file) to be used for testing and run evaluation:

   python valtest_gdan.py --config configs/cub.yml
