mlcourse.ai is an open Machine Learning course by OpenDataScience (ods.ai), 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 mlcourse.ai. The Russian version of the course is resurrected and will be led by Petr Ermakov. If you speak Russian, please refer to this Open ML course launching on Feb 1st, 2022.

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

Self-paced passing

You are guided through 10 weeks of mlcourse.ai. For each week, from Pandas to Gradient Boosting, instructions are given on which articles to read, lectures to watch, what assignments to accomplish.

Russian version of the course

The course originated in OpenDataScience, at that time in 2017 (well, and still), mostly Russian-speaking community. Hence the first couple of sessions were held in Russian. Then, later, the course launched in English and resulted in what you see here and on mlcourse.ai.

The Russian version of the course is resurrected and is led by Petr Ermakov. If you speak Russian, please refer to this Open ML course launching on Feb 1st, 2022.

Citing mlcourse.ai

If you happen to cite mlcourse.ai in your work, you can use this BibTeX record:

    howpublished = {\url{https://github.com/Yorko/mlcourse.ai}},


Discussions are held in the #mlcourse_ai channel of the OpenDataScience (ods.ai) Slack team.

The course is free but you can support organizers by making a pledge on Patreon (monthly support) or a one-time payment on Ko-fi.
