What do you need to understand for your thesis?

Research type thesis

You build a novel algorithm…

… but you need to know the prior theory, what has been done etc

Novel just means somehow interesting!

Computer Science: MSc Seminar Module

Goal

The goal of the module is to give students the opportunity to deepen their understanding of the field most interesting for them and to develop their communication skills.

​

Learning outcomes

After completing the module the student:

- is capable of independent work with modern research literature and other field-related material;

- can effectively communicate his knowledge of the field to others.
