What is a Datathon?

The Datathon is a weekend-long online competition where you are challenged to work on a real-world business case from the areas of computer vision, NLP and AI.

You and your team have 48 hours to come up with a solution to a real business challenge based on the provided datasets. The jury and the society will award the most precise, but also creative solutions.

The Datathon is entirely held online and opened to the global community via our platform. Anyone who wants to join us in Sofia is welcome.
