What we do...

Ensuring the quality of modern methods of machine learning with regard to predictive quality, robustness, impartiality and interpretability is often a challenge in practical applications. Our research focuses on:

  1. Comprehensive generation and selection of features for complex learning procedures (e.g. for use in online scenarios and taking into account different uncertainty factors).
  2. Robust predictive and explanatory mechanisms, taking into account various fairness definitions.
  3. Techniques for quantifying and improving the quality of (training) data.

Paper @ NeurIPS 2019 (HCML workshop)

"Towards User Empowerment" by Martin Pawelczyk, Johannes Haug, Klaus Broelemann and Gjergji Kasneci was accepted at NeurIPS' 'Human-Centric Machine Learning' workshop. The paper describes shortly a new way to to generate counterfactuals for heterogeneous data. Moreover, we also suggest how the quality of counterfactual suggestions can be evaluated.

Data Science Reading Group

For the first time in WS19/20, we are organizing a reading group on various topics from the field of machine learning and data science. DSAR team members alternately present interesting papers from their research areas. The first reading group will take place on Tuesday, 22.10.19, at 11 am on Sand 14 in room C207, and afterwards once every two weeks at the same time. A list of the topics will be continuously updated on our research page. All those interested are welcome to attend.
