  • First exam date changed; Results updated | 07.12.2018 17:26 | by Aleksei Tepljakov

    Dear Students,

    Please note that the date of the first exam had to be changed due to a secondment that the instructor must fulfill. The date has been pushed back two days and now is

    1. Jan 7th, 2019, 10.00.

    Sorry for the potential inconvenience!

    Also note that the results have been updated to reflect the status after the second test. Let me know if I missed filling in any details pertaining to the points awarded for timely submission of the lab work reports.

  • About symbolic regression in MATLAB | 05.12.2018 13:59 | by Aleksei Tepljakov

    Dear Students,

    As promised, I share with you my experience with fixing a backwards compatibility issue with the GPTIPS2F toolbox that I picked up the development of. The good news is, the support staff of MathWorks was supportive and the toolbox is now fully operational in both pre- and post-R2018a versions of MATLAB. Moreover, I have publically released it, so, if needed, you can pick it up at https://github.com/AlekseiTepljakov/gptips2f-matlab

  • Exam times during finals | 28.11.2018 17:13 | by Aleksei Tepljakov

    There are two slots that you can use to take the exam for this subject during finals:

    1. Jan 9th, 2019, 10.00.
    2. Jan 16th, 2019, 10.00.

    On the exam it is possible to do one of the following:

    • Redo test #1 or test #2;
    • Present your course project if you did not do it during the last weeks of the semester.
  • No lecture today | 28.11.2018 16:45 | by Aleksei Tepljakov

    Dear students,

    As I told you last week, there will be no lecture today. Next week we have Test #2 so you can use this free time to prepare for it.

  • Results page updated | 17.10.2018 14:45 | by Aleksei Tepljakov

    Dear students,

    You can now view the results of the first test in the table in the PDF file in the corresponding tab.

Description: 

The aim of the course is to give an overview of modeling and identification methods for solving static and dynamic problems such as optimal resource planning and industrial control. The major topics covered in the first part of the course include:

  • Static and dynamic models and applications.
  • Optimization. Linear programming. Convexity. Least squares. Newton's Method. Simplex method. Nelder-Mead method (applications).
  • Linear models. Time domain and frequency domain analysis.
  • Identification. Model types. Validation. Residual analysis.

In the second part of the course, the following contemporary modeling topics will be discussed:

  • Fractional-order modeling and control.
  • Artificial Neural Network based identification.
  • Global optimization methods. Genetic algorithms.
  • Fuzzy logic based modeling.

These topics will be delivered during several invited lectures and will be accompanied by corresponding practical works.

Most of the practical assignments of the course will be solved in MATLAB/Simulink environment. The first practice will be given on the 3rd week of the semester.

Policies: 

The learning outcomes of the course are evaluated in the following way:

  • Two tests, each giving 20% of the grade.
  • Five practice reports, each giving 2% of the grade.
  • An individual project report and presentation thereof giving 50% of the grade.
  • Bonuses: reports for practical works where a report is not required by default; other bonuses also possible.

All of these components are summed up at the end of the semester and form the exam grade.

The following policies are in effect:

  • There is only one attempt to do each of the tests during the semester. It is however possible to improve the result (if desired) during finals. Among the attempts, the one with the best grade will be counted as final.
  • The practice reports will cover topics from the second part of the course. The report for each practice must be submitted within two weeks of the date of carrying out the practical work in the laboratory. If a report is not received within the allocated time interval, the grade points for the practical work are not awarded.
  • Topics for the individual project may be selected from a list offered by the instructor, or proposed by the student. In the latter case, the topic of the project must be within the scope of the course. At the end of the course, a report for the project must be prepared and submitted for evaluation. The prospective length of the report is 15-20 pages.

Regarding the project, the student must also

  • Give short, 3-5 minute talks:
    • The first, describing his project idea, must be presented on the 3rd week of the semester;
    • The second, presented on the 6th week, must provide an update illustrating the progress;
  • Give a 10-12 minute talk about the finished project at the end of the course.

On all occasions, the instructor and other students may give feedback about the project.

The project may also be a work-in-progress. In such a case, the results obtained by the end of the course must clearly demonstrate the advances in the developed topic.
