This lecture teaches how to analyze large, high-dimensional, partially unreliable, and incomplete data using data analysis techniques and interactive visualizations that are tightly coupled. It explains the properties and parameters of important data analysis methods and shows how these methods can be integrated into Visual Analytics systems.

The interdisciplinary character of the development and use of Visual Analytics approaches is emphasized. This also includes questions of visual perception and cognitive processing of visual data and their role in decision-making processes. Special attention is given to the knowledge generation process, the process by which observations, hypotheses, statistical results and other artifacts are generated and managed. The application examples range from financial data (stock prices), data of credit card movements, gene expression data to epidemiological data and patient data. Target groups of such applications are investors, security departments, biologists, statisticians and physicians.

You can see an interview with Prof. Preim on the topic of Visual Analytics on Youtube.

Course of Lectures and Slides:


Similar to the lecture, the exercise will be performed virtually.

From 27.04. onwards, a new exercise sheet will be put online here every Monday. In the following week we will provide sample solutions for the current exercise sheet. There will be no voting for the exercises this semester. This means that the exercises are voluntary this semester. With regard to the exam, however, we advise everyone to deal with the exercises in detail every week.

For asking and answering questions about the lectures and exercises please use Moodle.

You can login with your student account at the university. There you will find a forum for each exercise sheet and lecture. Write your questions about the corresponding exercises/lectures and we will answer them. After providing the respective sample solution, you have 3 days to post questions about this exercise sheet in the corresponding forum. Afterwards, this forum will be closed. Please check before you ask a question of whether it is already answered in the forum.
