Course 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)
- Midterm theoretical colloquium
- Final exam
Kaggle
Link to competition is in slack
You should send reports before June 5 23:59 (Competition ends on the 4th of June, late submissions are not considered). Reports should be sent to the special form, that is going to be provided soon. Try to follow the format of report template - https://github.com/shestakoff/hse_se_ml/blob/master/2019/kaggle/kaggle-report-template.ipynb
Colloquium
Colloquium will be held on the 7th of April during seminar
You may not use any materials during colloquium, except single A4 prepared before the exam and handwritten personally by you (from two sides). You will have 2 questions from question list with 15 minutes for preparation and may receive additional questions or tasks.

Evaluation criteria
The course lasts during the 3rd and 4th modules. Knowledge of students is assessed by evaluation of their home assignments and exams. There are two exams during the course – after the 3rd module and after the 4th module respectively. Each of the exams evaluates theoretical knowledge and understanding of the material studied during the respective module.
Grade takes values 4,5,…10. Grades, corresponding to 1,2,3 are assumed unsatisfactory. Exact grades are calculated using the following rule:
- score ≥ 35% => 4,
- score ≥ 45% => 5,
- ...
- score ≥ 95% => 10,
where score is calculated using the following rule:
score = 0.7 * S_{cumulative} + 0.3 * S_{exam2}
cumulative score = 0.8 * S_{homework} + 0.2 * S_{exam1} + 0.2 * S_{competition}
- S_{homework} – proportion of correctly solved homework,
- S_{exam1} – proportion of successfully answered theoretical questions during exam after module 3,
- S_{exam2} – proportion of successfully answered theoretical questions during exam after module 4,
- S_{competition} – score for the competition in machine learning (it's also from 0 to 1).
Participation in machine learning competition is optional and can give students extra points.
"Automative" passing of the course based on cumulative score may be issued.
Kaggle competition 1
«Score» = ("your quality"-"baseline method quality") / ("max achieved quality" - "baseline method quality")
Required condition: a notebook with your best solution must be reproducible. Otherwise, you will not get any score.
Plagiarism
In case of discovered plagiarism zero points will be set for the home assignemets - for both works, which were found to be identical. In case of repeated plagiarism by one and the same person a report to the dean will be made.
Deadlines
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.
Structure of emails and homework submissions
Practical assignments must be implemented in Jupyter Notebook format, theoretical ones in pdf. Practical assignments must use Python 3 (or Python 3 compatible). 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!
