Data

1. Download metadata for birds coco and save them to data/

2. Download the birds image data. Extract them to data/birds/

   • cd data/birds
   • wget http://www.vision.caltech.edu/visipedia-data/CUB-200-2011/CUB_200_2011.tgz
   • tar -xvzf CUB_200_2011.tgz

3. Download coco dataset and extract the images to data/coco/

   • cd data/coco
   • wget http://images.cocodataset.org/zips/train2014.zip
   • wget http://images.cocodataset.org/zips/val2014.zip
   • unzip train2014.zip
   • unzip val2014.zip
   • mv train2014 images
   • cp val2014/* images

Pretrained Models

• IS for bird
  • python google_drive.py 0B3y_msrWZaXLMzNMNWhWdW0zVWs eval/IS/bird/inception_finetuned_models.zip
• FID for bird
  • python google_drive.py 1747il5vnY2zNkmQ1x_8hySx537ZAJEtj eval/FID/bird_val.npz
• FID for coco

Training

• go into code/ folder
• bird: python main.py --cfg cfg/bird_KDGAN.yml --gpu 0,1
• coco: python main.py --cfg cfg/coco_KDGAN.yml --gpu 0,1

Validation

1. Images generation:
   • go into code/ folder
   • python main.py --cfg cfg/eval_bird.yml --gpu 0
   • python main.py --cfg cfg/eval_coco.yml --gpu 0
2. Inception score:
   • go into eval/IS/bird folder
   • python inception_score_bird.py --image_folder ../../../models/bird_KDGAN_hard
   • or go into eval/IS/coco folder
   • python inception_score_coco.py ../../../models/coco_KDGAN_hard
3. FID:
   • go into eval/FID/ folder
   • python fid_score.py --gpu 0 --batch-size 50 --path1 bird_val.npz --path2 ../../models/bird_KDGAN_hard
   • python fid_score.py --gpu 0 --batch-size 50 --path1 coco_val.npz --path2 ../../models/coco_KDGAN_hard
