ODS stickers – Open Machine Learning Course

License: CC BY-NC-SA 4.0 Slack Donate Donate is an open Machine Learning course by OpenDataScience (, led by Yury Kashnitsky (yorko). Having both a Ph.D. degree in applied math and a Kaggle Competitions Master tier, Yury aimed at designing an ML course with a perfect balance between theory and practice. Thus, you go through math formulae in lectures, and practice with Kaggle Inclass competitions. Currently, the course is in a self-paced mode. Check out a thorough Roadmap guiding you through the self-paced

Bonus: Additionally, you can purchase a Bonus Assignments pack with the best non-demo versions of assignments. Select the "Bonus Assignments" tier. Refer to the details of the deal on the main page

Mirrors (:uk:-only): (main site), Kaggle Dataset (same notebooks as Kaggle Notebooks)

Self-paced passing

The Roadmap will guide you through 11 weeks of For each week, from Pandas to Gradient Boosting, instructions are given on what articles to read, lectures to watch, what assignments to accomplish.
