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:

  1. Lectures and seminars
  2. Practical and theoretical homework assignments
  3. A machine learning competition (more information will be available later)
  4. Theoretical colloquiums: midterm and final.
  5. Final written exam

Syllabus

  1. Introduction to machine learning.
  2. K-nearest neighbours classification and regression. Extensions. Optimization techniques.
  3. Decision tree methods.
  4. Bayesian decision theory. Model evaluation:
  5. Linear classification methods. Adding regularization to linear methods.
  6. Regression.
  7. Kernel generalization of standard methods.
  8. Neural networks.
  9. Ensemble methods: bagging, boosting, etc.
  10. Feature selection.
  11. Feature extraction
  12. EM algorithm. Density estimation using mixtures.
  13. Clustering
  14. Collaborative filtering
  15. Ranking

Evaluation criteria

The course lasts during module 3 and 4. The grade for the course is formed by theoretical knowldege and practical skills. Theoretical knowledge will be evaluated by the final exam (at the end of module 4) and intermediary exam (at the end of module 3). Paractical skills will be evaluated by the grades for the howework assignements during the course.

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

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!
