Welcome to the pages of the working group Applied Computer Sciences headed by Prof. Dr. Jörg Frochte. The working group is assigned to the Department of Electrical Engineering and Computer Science and is primarily active at the Velbert/Heiligenhaus campus. The focus of our activities in teaching and research is on the two topics
- Machine Learning and Data Mining
- Modeling and Simulation
In the field of machine learning and data mining, the working group is active in the Bergische Innovationsplattform für Künstliche Intelligenz (Bergische Innovation Platform for Artificial Intelligence) and networked with scientists from the Bergische University of Wuppertal within the interdisciplinary center "Machine Learning and Data Analytics". In addition, we maintain collaborations with colleagues from Weimar, Leipzig, Lemgo, Wellington (New Zealand) ...
Since 2019/20, the group is also particularly active in the continuing education project WeAI of the Bochum University of Applied Sciences, which offers computer scientists, engineers and natural scientists in the field of Machine Learning a practical form of continuing education at the highest professional level.
Members of the working group
Positions as research/ student assistant
A research assistant is usually a person who already has a bachelor's degree and is enrolled in a master's program. A student assistant is a person enrolled in a Bachelor's program without a degree.
There are currently no open vacancies for research/ student asssistants in AKIS or the participating research groups.
Field of Interest
The working group is so far active in the areas of:
- Simulation Data Mining: application of data mining to data sets from simulations.
- Educational data mining: application of data mining to learning and examination data
- Machine learning in the area of autonomous robots in cooperation with colleague M. Schmidt
- Machine learning and AI in the area of computer games and virtual environments
Furthermore, we are always open for new exciting applications in the field of machine learning.
Research & Development projects
Currently, we are working in the area of "machine learning" on the following two topics:
- Learning of Ill-Posed Problems
- Learning on Vertically Partitioned Data

TIMALIE - TIered MAchine Learning ArchItEctures (2019 - 2022)
The research inthis project focuses on staged learning approaches. Using the approaches explored, we aim to make progress in the following problem areas:
- Learning Autonomous Systems with Limited Resources.
- Privacy & data security in cloud learning
- Improved handling of incomplete data sets
The project is part of the Bergische Innovation Platform for Artificial Intelligence. This project is funded by the European Regional Development Fund (ERDF).
DIBS- Data Mining for Student Advising (2015-2016)
DIBS (Data MIning for Student Advising) is an american slang expression and could probably best be translated in German as "First!" as an exclamation. In this sense, the aim is to implement approaches that make it possible to identify risks of dropping out at an early stage. For this purpose, a first study was carried out with special consideration of data protection and data security in learning systems and procedures. The project was funded by the state of North Rhine-Westphalia.
SimCloud (2012-2015)
SimCloud is a project supported by the BMBF (Federal Ministry of Education and Research) for the integration of a finite element simulation into a cloud architecture. The goal is to realize an integrated workflow for a cloud-based FEM application in a prototype. Essential aspects are security and user support. For the distribution to hetrogenic structures we made intensive use of machine learning techniques. The project was funded by the BMBF.

Interested in writing a thesis in applied computer science?
If you are a student of the Bochum University of Applied Sciences and are thinking about writing a bachelor's or master's thesis with me, you can inform yourself about the focus of the working group on the pages Projects and Theses, Research and Development, and Publications. In general, in my experience, the following applies: If you come up with your own idea or if we find a topic together that you are really interested in, the results will generally be good. So if your topic does not appear in the topics on these pages, don't let this scare you off at first, just present your idea.
Concerning the form, the same hints apply as below for the term papers. If you are unsure, it is best to address the open questions directly at the beginning of the paper.
The working group regularly offers the option of carrying out Communication and Information Systems, Software and Development projects in our focus areas. Suggestions for topics are regularly posted in the showcases. Of course you are also welcome to come up with your own ideas.
Students of computer science from Bochum with an interest in machine learning or applied AI are of course also welcome for their software projects, etc.
Here you will find a rough orientation for writing a final paper or term paper, as pdf and as well as a complete LaTeX template (zip).
Please consider this example only as an orientation guide. It should give you an impression of how a paper is typically structured and which classic mistakes (see e.g. note on handling sources and citations at the bottom of the page) should be avoided. Also the basics do not always have to be called basics, but can be modified as a heading to suit the paper.
Of course you do not have to use LaTeX. If you want to use Word or LibreOffice you can simply follow the pdf above.If you want to use LaTeX under Windows I recommend MiKTeX.
Please note that form and citation technique are important things in such papers and will also be reflected in the grade. Take the hints to heart.
