Note:

• To reproduce the results of the paper, you just need to run codes in the experiments folder.
• Multi-Lable datasets will be automatically downloaded for the firs time.
• For criteo dataset, in the first time, use the script experiments/Criteo/criteo_dataset/create_datasets.ipynb

(A) All you need to begin with:

1: Run 1_build_an_encoder.ipynb.

2: Run 2_a_synthetic_exp.ipynb.

(B) For Criteo dataset:

In the directory experiments/Criteo/, we have already run this file for the experiment we have reported in Figure 7 and provided dataset by processing nrows=1000000000, that uses 1 billion rows of the original dataset.

I If one desires to make a dataset of another nrows, for the first time, the script create_datasets.ipynb should be used. You should first set this parameter (number of rows) in the create_datasets.ipynb, build the dataset, and then run the Criteo experiment. Please see create_datasets.ipynb for more dtail.

(C) Info:

You may need to install packages that are listed in the requirements.txt file.

% pip install -r requirements.txt 

Specifically, these libraries:

%pip install iteround
%pip install pairing
