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.

Lecture

We would prefer to hold the lectures and one of the exercise sessions in presence, however, we will adapt to the corona situation at the given time.
We will post the necessary information regarding the lecture and exercise sessions here on the website.

In addition to the synchronous lectures, you can find the lecture video recordings from a previous year below. You may use them as a supplement, they do not introduce information beyond the synchronous lecture.

Note: There will be no lecture on the 09.05.2022 and the 23.05.2022. During this time, please watch the videos “Scatterplot-Based Visual Representations Part 1 | Part 2 | Part 3”.

Location: G29-307
Time: Mo., 11:00 – 13:00 (weekly) (→ see LSF)
1. Lecture (in presence): 04.04.2022

Exercise

We plan to hold the Wednesday exercise session in presence and the Thursday exercise session via Zoom.

From 18.04. onwards, a new exercise sheet will be put online here every Monday. In the following week, you will have to vote for the tasks for which you feel able to present your solution in your corresponding exercise session. At the end of the semester, you have to have voted for at least 67% of the exercise tasks to be allowed to take the exam.

The voting will take place via Moodle.

You have to sign up for an exercise group until the 01.04. via LSF.
