Content

The VU Visual Data Science will discuss how techniques from visualisation and visual analytics can be applied in data science. The lecture will start with a theoretical introduction to different concepts of visualisation and visual analytics. The second part of the lecture will deal with the practical application of Visual Data Science, namely the selection of charts, and trust in visualisations. An overview of current applications and libraries will be given. The lecture part then concludes with the late-breaking research topics of trust in visual interpretation and how AI methods are used in visualisation.

Lectures

Important information about the lectures:

  • All lectures are hybrid and will be recorded.
  • Lectures will be only 60min. The remaining 30min minutes will be dedicated to solving practical questions in TUWEL. This can be done either directly in the lecture room afterwards, or later on.
  • The first slot (Oct 5th) is only an introduction to the administrative structure of the lecture (no lecture unit).
  • One lecture (Oct 19th) will be presented as a pre-recorded video in TUWEL, since Johanna Schmidt is at the conference on that day.
  • Hybrid lectures usually take place in FAV Hörsaal 3 Zemanek, except for the lecture number 5 (Nov. 23), which will take place in Seminarraum Argentinierstraße (HS 3 is taken on that day).

Lab Part

Lab organisation and submissions are done via TUWEL.

The lab part of the VU outlines the different stages of a data science workflow. Every data science workflow consists of five stages: Discover, Wrangle, Profile, Model & Report. We will work on all stages and see how visualization can be used in every stage (except Discover). The lab part has the following deadlines:

# Date & Time Description
D1 09.11.2022 23:59 Selection of topic & stage Discover finished - submission of short report (1 A4 page).
D2 14.12.2022 23:59 Stages Wrangle and Profile finished - submission of report (at least 3 A4 pages).
D3 11.01.2023 23:59 Stages Model finished - submission of report (at least 3 A4 pages).
D4 16.01.2023 - 20.01.2023 Final presentations (with dashboard from stage Report).
