About us:


Model selection and model averaging are two important techniques to find statistical models with good properties. While many approaches have been proposed for complete data, it is often unclear how to proceed with data with missing values. In collaboration with our partners in South Africa (Dr. Michael Schomaker), we have proposed several approaches using multiple imputation. Furthermore, we have combined multiple imputation with resampling (bootstrap) to get confidence intervals with reasonable nominal coverage.

A part of our group is currently working in the field of Natural Language Processing (NLP). We are specifically interested in the comparability and evaluating/benchmarking large pre-trained language models used for transfer learning. We are also particularly interested in the use of such models as potential substitutes for traditional knowledge bases.
