Group Members

Jilles is the leader of the Independent Research Group on Exploratory Data Analysis at the DFG Cluster of Excellence on Multimodal Computing and Interaction at Saarland University. In addition, he is affiliated as Senior Researcher with the Database and Information Systems group of the Max Planck Institute for Informatics.

His research is mainly concerned with exploratory data mining. That is, developing theory and algorithms for summarising data in easily understandable terms. To identify what you need to know, i.e., what is the most interesting structure in the data, he often employs information theoretic methods. In particular, the principles of Minimum Description Length (MDL) and Maximum Entropy have proven to be highly valuable tools.

Currently he is investigating techniques for identifying informative local structures in large collections of complex data; how to efficiently mine good data descriptions directly such data; how to mine very large graphs, including characterising influence propagation in social networks; and, last but not least, how to determine cause and effect, i.e. causal inference and modelling.
