Project Structure

• train.py: main entry point of the program, used to run different experiments
• utils.py: a set of utility functions
• test_cifar.sh: a simple script to run GI experiment for the CIFAR-10 dataset
• README.md: this readme file
• environment.py: conda environment settings
• data.py: load and preprocessing for different datasets
• otherwork/: source code from other work (with some modifications to integrate)
• models/: pytorch model architectures and modules
• imputers/: training process for different imputers

Note: as shown in the example below, always fix the hash seed. We use python hashing to fingerprint samples.
