Course Syllabus


Machine learning is the field of study that helps us to find the dependencies in data automatically. Such a technology enables to solve different problems without explicit programming of rules. Due to advances in computing and the field itself, during last decade machine learning has become an essential feature of products ranging from web-services to banks. In this course the student is going to overview the essential concepts of machine learning and then practice employing machine learning methods to solve business tasks. This course emphasizes the practical part and considers various aspects of solving real-world problems. The course content covers all the popular methods such as linear methods, gradient boosting, and neural networks. Finally, the course considers the best practices of major companies leveraging the machine learning technology.

Assessment Elements

Assessment Elements

  • Partially blocks (final) grade/grade calculation Homework
    A student should provide a Jupyter notebook.
  • Partially blocks (final) grade/grade calculation Homework
    A student should either provide a Jupyter notebook to the professor, or participate in an in-class Kaggle competition.
  • blocking Written exam
    Format: the exam is taken written (programming assignment). Platform: the exam is taken using MS Teams platform. Students are required to submit their assignment during the exam session (and no later). To join the exam in MS Teams students' hardware should meet the following requirements: https://docs.microsoft.com/ru-ru/microsoftteams/hardware-requirements-for-the-teams-app. A student is supposed to: check hardware compliance no later than 7 days before the exam; sign in with their corporate account; check the ability to join the meeting. If one of the requirements can't be met a student is obliged to inform a professor and a manager of a program 2 weeks before the exam date. Students are not allowed to involve any other person in their programming assignment. Any interaction with other students that gives advantage on the assignment is prohibited and so is any plagiarism in the programming assignment. Students are allowed to use any Internet resources and clarify their assignment with the professor.
  • Partially blocks (final) grade/grade calculation MOOC
    A student is graded in a binary way based on the completion of the MOOC.
