Data Science and Artificial Intelligence

Data Analysis and Data Quality

Integrated course, 5.00 ECTS


Course content

At the beginning of the course, Data Analysis & Cleaning will be presented as a process step in the process model of Computational Intelligence. Following the presentation of current data models and structures, an introduction to Exploratory Data Analysis including the presentation of standard graphical methods of this area will be given. It then introduces the central concept of data quality and metrics to measure data quality aspects. Finally, the individual phases (screening, diagnosis, treatment, ...) and methods (detection of typical errors such as missing values, outliers, obvious inconsistencies, etc. by means of data mining and their removal such as simple transformation, deductive correction, missing Data Imputation) of Data Cleaning are shown. In the tutorial, Data Cleaning will be demonstrated by using R and the Hadoop Toolchain.
