The Differential Privacy Synthetic Data Challenge

Phase 2 will entail a sequence of three marathon matches run on the Topcoder platform, asking contestants to design and implement their own synthetic data generation algorithms, mathematically prove their algorithm satisfies differential privacy, and then enter it to compete against others’ algorithms on empirical accuracy over real data, with the prospect of advancing research in the field of Differential Privacy.

The first Marathon Match will run from October 31, 2018 to November 30, 2019.

This initiative is the first of its kind in differential privacy and offers a unique opportunity to benchmark implementation systems against each other. Our hope is that this challenge will be a catalyst to advance the state of the art in Differential Privacy and create systems that can be implemented to generate publicly releasable datasets for Public Safety and other industries.

Competitors may enter the contest at any point to participate between November 2018 and April 2019. Topcoder will be running three separate Marathon Matches and will bring the registrations from previous matches to the next matches.
