    Models & Algos

    Topcoder has over 15 years of experience building data science models and algorithms with the help of our members. In that time we’ve amassed some impressive capabilities in our algorithmic library. As an open community, we feel it is only right to give them back to you to reuse, repurpose, reshape, and improve upon!

    We are launching this page with the SpaceNet algorithms but have many more on the way, so stay tuned as we continue to expand our models and algo library!
