The Majority Vote Paradigm Shift: When Popular Meets Optimal

The code is written in Python 3 and is based on the use of Jupyter.

Install the required packages using:

pip install -r requirements.txt

Download the required datasets:

python3 download_data.py

To run the code to obtain all subfigures of Figure 2 and Figure 3 from the paper:

Run all computations.ipynb

To run experiments on synthetic data and obtain results as in Table 2:

python3 syntethic_exps.py

To run experiments on real data and obtain results as in Table 2:

python3 real_exps.py

To run experiments to obtain Figure 4 (from the main) and Figure 2 (from the Appendix):

python3 check_bound_looseness.py

To run experiments to obtain Table 1 from the Appendix:
