Requirements

• Python 2.7
• Tensorflow-1.0.1
• Keras-2.0.0
• numpy
• h5py

Usage

To run the experiment with the (grayscaled) SVHN dataset as the source domain and the MNIST dataset as the target domain

python main_sm.py

The core algorithm is implemented in drcn.py. Data augmentation and denoising strategies are included as well.

Results

The source to target reconstruction below (SVHN as the source) indicates the successful training of DRCN.

python reconstruct_images.py

The classification accuracies of one DRCN run are plotted as follows -- the results may vary due to the randomness:
