Optimization of Adaptive Systems - Theory of Machine Learning
The adaptive systems workgroup is concerned with the design and analysis of biologically-inspired, 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.
Currently we are working on
- learning in "deep", hierarchical networks
- fast training and model selection for support vector machines
- 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 computational intelligence to other research groups and industrial partners.
Example: The animation on the right depicts a sequence of support vector machine hypotheses for a two-class classification problem.
Please see our complete list of publications here.
We provide and maintain a fast, modular C++ library for the design and optimization of adaptive systems. It features methods for nonlinear optimization, in particular single- and multi-objective evolutionary algorithms and unconstraint gradient-based algorithms, as well as machine learning methods including various types of neural networks and kernel-based algorithms such as SVMs. The Shark library works under SunOS/Linux, Mac OS X, and Windows.
Shark can be downloaded from The official Shark-Project Site at the SourceForge open source development and download repository. Please also see the pre-release version of Shark 3 here (we advocate starting directly with Shark 3, as Shark 2 support will fade out in the future).
Also see Christian's software page at DIKU for additional software related to Shark.
