Theory of Machine Learning

The optimization of adaptive systems workgroup is concerned with the design and analysis of adaptive information processing systems. We are interested in systems that improve over time through learning, self-adaptation, and evolution. Our systems improve autonomously based on data, in contrast to manual instruction or programming.

Parameter tuning for a support vector machine

Currently we are working on

fast training and model selection for support vector machines
learning in deep networks
development of new evolutionary search algorithms and their analysis
open source implementation of a large number of machine learning algorithms

We offer theoretical and practical advice in machine learning and computational intelligence to other research groups and industrial partners.

Software: Shark

We provide and maintain a fast, modular, open source C++ library for the design and optimization of adaptive systems. It provides a diverse set of machine learning algorithms as well as methods for non-linear optimization. The Shark library works under SunOS/Linux, Mac OS X, and Windows. Shark can be downloaded from shark-ml.org.

Masters theses in the areas of machine learning and optimization

Prof. Dr. Tobias Glasmachers

I am regularly offering master's thesis topics in the areas of machine learning and evolutionary and gradient-based optimization.

Master Thesis

About the INI

The Institut für Neuroinformatik (INI) is a central research unit of the Ruhr-Universität Bochum. We aim to understand the fundamental principles through which organisms generate behavior and cognition while linked to their environments through sensory systems and while acting in those environments through effector systems. Inspired by our insights into such natural cognitive systems, we seek new solutions to problems of information processing in artificial cognitive systems. We draw from a variety of disciplines that include experimental approaches from psychology and neurophysiology as well as theoretical approaches from physics, mathematics, electrical engineering and applied computer science.
