Main Requirements

Prepare data

  1. Download the preprocessed metadata for birds and coco and save them to data/
  2. Download birds dataset and extract the images to data/birds/
  3. Download coco dataset and extract the images to data/coco/

Pre-trained DAMSM model

  1. Download the pre-trained DAMSM for CUB and save it to DAMSMencoders/
  2. Download the pre-trained DAMSM for coco and save it to DAMSMencoders/

Trained model

you can download our trained models from our onedrive repo

Start training

Run main.py file. Please adjust args in the file as your need.

Evaluation

please run IS.py and test_lpips.py (remember to change the image path) to evaluate the IS and diversity scores, respectively.

For evaluating the FID score, please use this repo https://github.com/bioinf-jku/TTUR.

Performance

You will get the scores close to below after training under xe loss for xxxxx epochs:
