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 topicReading and understanding scientific articlesSummarizing and explaining (orally and/or written)Comparing and discussingPractice to give a talk or to write a reportExperience critical scientific discussion

Tasks

(Pre)requirements„Grundlagen Methodischen Arbeitens“Basic knowledge in CG (“CG1” lecture)Attend 3 lectures:

„Wie halte ich einen Vortrag“ (Prof. Purgathofer), Monday, 16.05. at 14:00, in HS7„Forschung und wie sie funktioniert“ (Prof. Gröller), Friday, 11.03. at 14.15 in EI2„Wie schreibt man eine wissenschaftliche Arbeit “ (Prof. Breiteneder), Friday, 15.04. at 14:15 in EI2

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 (no more than 2-3) You explain your progress to other participants Idea: teach you scientific communication skillsLanguage: (typically) German or in English

Two options for presenting your results:Final talk (20 min + 5 min discussion) in English

The best talks will be invited our KonversatoriumOR written report in English (8-10 pages)
