Mission statement

Learn basic scientific work flow (in CG) and improve scientific communication skills

Practice to review literature and get familiar with a particular scientific topic: reading and understanding (difficult) scientific articlesSummarizing and explaining (orally / written)Comparing and discussing: experience critical scientific discussionPractice to give a talk or to write a report

3

Tasks

(Pre)requirementsBasic knowledge in CG (“CG1” lecture)Attend 3 lectures:

„Forschung und wie sie funktioniert“ (Prof. Gröller), 9.11. at 5 PM in this room„Wie halte ich einen Vortrag“ (Prof. Purgathofer), 16.11. at 5 PM in this room„Wie schreibt man eine wissenschaftliche Arbeit “ (Prof. Wimmer), 23.11. at 10:30 AM in this room

Procedure

Analyze some recent papers (select with advisor) Literature study relevant for paper understanding Paper results evaluation: compare with existing results / code from the web / implement it (if reasonable amount of work)

Does the algorithm work as described?How do parameters influence the result?When does the algorithm fail? (models/images/etc) How fast is the algorithm on current hardware?

Stefan Jeschke

5

Procedure

There will be regular meetings (about 6) with the advisor

Small student groups (2-4) You explain your progress to other participants Idea: teach you scientific communication skillsLanguage: (typically) German or in English
