[zur Übersicht]

Wintersemester 2020 / 2021

Lectures: Wednesday, 10:00 to 11:30

Dates and syllabus below

Topics in this course

  • Data Collection Methods and Ethics
  • Data Analytics: Mainly Statistics & Probability Theory (Descriptive Statistic, Bayesian versus Frequentist thinking, Statistical Inference, Causal Inference)
  • Data Visualizations, Interpretations and Data Story Telling
  • Multimedia Data and Deep Learning

Tutorial: Wednesday, 14:00 to 15:30

  • You will get hands-on experience and learn practical data science (e.g. how to do data science in python)
  • Paper and pen exercises, small programming exercises, reading homework.
  • Try to solve the problems yourself before the exercise class (self-assessment: how well have I understood the content of the lecture? Use exercise class to ask open questions). You don’t have to hand in exercise sheets. But bring them to class since we correct them together.
  • Online Q&A will be added to make up for Corona distancing. Format to be announced


  • First exam: 2021.02.12
  • Second exam: 2021.03.12


Exam reviews are cancelled.

A basic understanding of programming that will allow you to manipulate data and implement basic algorithms. Python will be the “official” programming language used during the hands-on sessions. We will use IPython Notebook as the environment. A basic understanding of statistics and algebra will help too.
