To reproduce the experiments for IHDP and MNIST dataset:
1. Run IHDP_experiment.ipynb for IHDP dataset
  - dataset is required to download in Data/IHDP,
  - can be downloaded from https://www.fredjo.com/
2. Run MNIST_experiment.ipynb for MNIST dataset
  - given the limited size, the pretrained models can not be uploaded
  - the model need to be trained from the source domain data
