[убрать]Class description
In this class we consider the main problems of data mining and machine learning: classification, clustering, regression, dimensionality reduction, ranking, collaborative filtering. We will also study mathematical methods and concepts which data analysis is based on as well as formal assumptions behind them and various aspects of their implementation.
A significant attention is given to practical skills of data analysis that will be developed on seminars by studying the Python programming language and relevant libraries for scientific computing.
The knowledge of linear algebra, real analysis and probability theory is required.
The class consists of:
- Lectures and seminars
- Practical and theoretical homework assignments
- A machine learning competition (more information will be available later)
- Theoretical colloquiums: midterm and final.
- Final written exam
Class program

Отчётность по курсу и критерии оценки
Оценка за курс. Итоговая оценка за курс складывается из оценок за домашние задания, оценок за коллоквиумы и оценки за экзамен. Оценка за соревновательное задание будет являться бонусной. Точные критерии оценивания будут выложены позднее.
Стандартно практические здания оцениваются по 5-бальной шкале, а теоретические — по 3-бальной.
Плагиат. Всем, у кого обнаружен плагиат ставится 0 баллов и отметка о плагиате. И тем, кто списал, и тем, у кого списали. Мы не будем искать первоисточник работы. Также Вы должны понимать, что плагиат будет иметь и другие последствия. При обнаружении плагиата у одного и того же человека более одного раза на него будет оформляться докладная на имя декана.
Deadlines
All the deadlines can be found in the second tab here.
We have two deadlines for each assignments: normal and late. An assignment sent prior to normal deadline is scored with no penalty. The maximum score is penalized by 50% for assignments sent in between of the normal and the late deadline. Assignments sent after late deadlines will not be scored (assigned with zero score) in the absence of legitimate reasons for late submission which do not include high load on other classes.
Standard period for working on a homework assignment is 2 and 4 weeks (normal and late deadlines correspondingly) for practical assignments and 1 and 2 weeks for theoretical ones. The first practical assignment is an exception.
Deadline time: 23:59 of the day before seminar (Sunday for students attending Monday seminars and Wednesday for students that have seminars on Thursday).
Structure of emails and homework submissions
All the questions and submissions must be addressed to cshse.ml@gmail.com. The following subjects must be used:
- For questions (general, regarding assignments, etc): "Question - Surname Name - Group(subgroup)"
- For homework submissions: "Practice/Theory {Lab number} - Surname Name - Group(subgroup)"
Example: Practice 1 - Ivanov Ivan - 131(1)
If you want to address a particular teacher, mention his name in the subject.
Example: Question - Ivanov Ivan - 131(1) - Ekaterina
Please do not mix two different topics in a single email such as theoretical and practical assignments etc. When replying, please use the same thread (i.e. reply to the same email).
Practical assignments must be implemented in ipython notebook format, theoretical ones in pdf. Practical assignments must use Python 2.7. Use your surname as a filename for assignments (e.g. Ivanov.ipynb). Do not archive your assignments.
Assignments can be performed in either Russian or English.
Assignments can be submitted only once!
