This course introduces fundamental concepts and techniques of interactive-visual data analysis (IVDA). The main focus is on the combination of automatic data analysis methods with interactive visual interfaces, as well as on their interplay to facilitate data analysis goals. As such, IVDA is particularly suited to leverage the strengths of both humans and machines in a human-in-the-loop data analysis process. Associated research fields are Information Visualization, Visual Analytics, Interactive Data Science, Interactive Machine Learning, and Human-Centered Artificial Intelligence.
Students will learn basic characteristics of data types and data attributes (WHAT), as well as data analysis tasks (WHY). Further, students will learn basic design skills about HOW data can be transformed into visual structures and which types of visualization techniques are meaningful design choices for given data types and analysis at hand. Students will also learn fundamental interaction techniques, as well as concepts for the composition of views in data analysis systems for different data types and their individual complexities.
Further, students will gain a deep understanding about how data analysis can benefit from both having a human and a (machine learning) model in the loop, following the goal to gain knowledge from data.Along these lines, students will learn about the strengths (and weaknesses) of human and machines, as well as about combining these complementary strengths effectively, as described in Visual Analytics methodology. In detail, students will learn examples for interactive data preprocessing, human-centered unsupervised machine learning, as well as for human-centered semi-supervised and supervised machine learning. Finally, the course introduces approaches that allow training personalized machine learning models and conduct personal and human-centered data analytics and artificial intelligence.
This module is designed for MA students (POC, DS, AI). It would be possible for students in other disciplines to take this course with a programming background. There are no enforced prerequisites, but the willingness to participate actively and to work in groups is recommended.
The course requires some degree of Student groups should be comfortable with frontend and backend development. Basic knowledge in data science, machine learning, and data analysis are useful but not mandatory.programming expertise.
