Three Challenges



The TunedIT project was established in 2008 as a free and open experimentation platform for data mining scientists, specialists and programmers. It was extended in 2009 with a framework for online data mining competitions, used initially for laboratory classes at universities. Today, we provide a diverse range of competition types - for didactic, scientific and business purposes.

  • Student Challenge — For closed members groups. Perfectly suited to organize assignments for students attending laboratory classes. Restricted access and visibility, only for members of the group. FREE of charge
  • Scientific Challenge — Open contest for non-commercial purpose. Typically associated with a conference, journal or scientific organization. Concludes with public dissemination of results and winning algorithms. May feature prizes
  • Industrial Challenge — Open contest with commercial purpose. Intellectual Property can be transfered at the end. No requirement for dissemination of solutions
