Useful insights from data

The EDA group at LIACS, headed by dr. Matthijs van Leeuwen, develops algorithms and tools that enable domain experts to explain what is in their data by finding interpretable patterns and models.

Whether data analysis is exploratory or predictive, it is more useful if the methods are explainable and the results interpretable: explanatory data analysis. Our main focus is on data exploration, as people are often interested in discovering novel and unexpected patterns, but we also investigate prediction that is both accurate and transparent. More technically, our research builds on the state of the art in information theoretic data mining, statistical pattern mining, and interactive data exploration and analytics.

Apart from fundamental data mining research, we collaborate on multidisciplinary data science projects to demonstrate the impact of our research on society. Examples include the Leiden Data Science Research Programme on scientific data, and the SAPPAO project on airline data.
