Maschinelles Lernen

Machine learning

Exam SS 2019

The grades have been sent to the ZPA. Exam review will be on Tuesday 17.9 between 1pm and 2pm. Afterwards, it will only be possible during the consultation times (Mondays 1pm-2pm) in the lectures period (after 14.10).

Important information

The Machine Learning (573050) course will not be offered anymore, starting from the winter semester 2019-2020.

It is replaced by the Neurocomputing (573180) course: https://www.tu-chemnitz.de/informatik/KI/edu/neurocomputing.

All students having Machine Learning in their study program (Studienordnung) can take Neurocomputing as a replacement, as confirmed by the respective study commissions. Erasmus students can simply modify their learning agreement accordingly.

The content of Machine Learning and Neurocomputing strongly overlap. Only reinforcement learning has been moved to a new course called Deep Reinforcement Learning (573140) https://www.tu-chemnitz.de/informatik/KI/edu/deeprl, available for a selection of Master programs (Informatik, Neurorobotik, Data Science).

Open topics

There is an open topic on large-scale statistical face modeling, in co-supervision with Martin Grewe from the Zuse Institut Berlin (ZIB): pdf. Contact Julien Vitay if you are interested.
