Generating Images with Recurrent Adversarial Networks

Python (Theano) implementation of Generating Images with Recurrent Adversarial Networks code provided by Daniel Jiwoong Im, Chris Dongjoo Kim, Hui Jiang, and Roland, Memisevic

Generative Recurrent Adversarial Network (GRAN) is a recurrent generative model inspired by the view that unrolling the gradient-based optimization yields a recurrent computation that creates images by incrementally adding onto a visual “canvas”. GRAN is trained using adversarial training to generate very good image samples.

Generative Adversarial Metric (GAM) quantitatively compare adversarial networks by having the generators and discriminators of these networks compete against each other.

How to set-up LSUN dataset

1. Obtain the LSUN dataset from fyu's repository
2. Resize the image to 64x64 or 128x128.
3. Split the dataset to train/val/test set.
4. Update the paths in provided paths.yaml, and run the script

python to_hkl.py <toy/full>

Link it to the inquire/main file, e.g.

lsun_datapath='/local/scratch/chris/church/preprocessed_toy_10/'

How to run

Entry code for CIFAR10 and LSUN Church are

    - ./main_granI_cifar10.py

How to obtain samples with pretrained models

First download the pretrained model from this Dropbox Link, save it to a local folder, and supply the path when prompted.

    python inquire_samples.py # to attain Nearest Neighbour and Sequential Samples

    python main_granI_lsun.py # to attain 100 samples from the pretrained model.
