Data Mining II (FSS 2021)

Building on the Data Mining fundamentals course, this course deepens the theory and practice of advanced data mining topics, such as:

  • Data Preprocessing
  • Dimensionality Reduction
  • Anomaly Detection
  • Time Series Analysis and Forecasting
  • Parameter Tuning
  • Ensemble Methods
  • Neural Networks and Deep Learning
  • Model Validation

The course consists of a lecture together with accompanying practical exercises as well as student team projects.  In the exercises the participants will gather initial expertise in applying state of the art data mining tools on realistic data sets.

Like in the previous years, participants will take part in the annual Data Mining Cup (DMC), an international student competition in data mining, as part of the project work. In addition to the DMC submission, the approaches and results of the project have to be compiled into a written project report, and presented in a plenary session.

Exam Review

The exam review for the retake exam of FSS2021 will take place on Thursday, 04 November 2021, starting from 08:00. You have to register for the exam review by writing a mail to Bianca Lermer until Thursday, 28 October 2021. We will then allocate a time slot for the review to you.

Time and Location

Until further notice, the lecture and exercise are conducted fully virtually.


We'll have two alternatives for the exercise:


  • Lecture Slides

  • Participation

    • The course is open to students of the Master Business Informatics, Master Data Science, and Lehr­amt Informatik.
    • Registration is done via Portal2.
    • In case there are more registration than places (64), places will be allocated automatically by Portal2.
  • Outline

    Note:The lecture starts the lecture in the second week, i.e., on March, 9th. The exercises will then begin on March, 15th.

    18.06.: Internal submission of reports and solutions (prequisite for taking part in the exam)

    29.06.: Official submission of solutions

    Note: we will be available for consulting and feedback to those who still want to tune their solutions after the exam period. On June 28th, we will select the two solutions to submit to the DMC.
