Intelligent Systems for Complex Data Research Group

We find patterns in data and mine information from complexity

Research & Research Areas

We are a team of researchers at Masaryk University in Brno, Czech Republic, specializing in complex data analysis. As part of the DISA laboratory and in close collaboration with the CERIT-SC centre, we aim to discover patterns within vast amounts of complex data.

We tackle unique challenges ranging from exploring patterns in images to the intricate analysis of complex biological structures such as proteins. Our ambition is to redefine the boundaries of effective and efficient processing of large datasets by leveraging our proficiency in machine learning, data mining, and clustering techniques.

We are constantly looking for new members, postdocs, students for bachelor's and master's theses and more!

We've introduced a Learned Metric Index – an index for complex, unstructured or high-dimensional data built as a structure of machine-learning models. 

No description

We develop our own application for searching in proteins by their structural similarity called AlphaFind.​

Adhering to the Open Science principles, we publish our work without restrictions, and the Learned Metric Index Framework is available online on GitHub.

Our Collaborations and Outreach

In our team, we strive to develop cooperation with other research teams from both Czechia and abroad. Our most prominent partners are:

No description

Information Systems and Data Mining Research Group, CAU University of Keil, Germany. Together with Prof. Dr. Peer Kruger and his group, we investigate modern techniques for indexing, searching and solving (reverse) kNN data retrieval techniques.

No description

Biological Data Management and Analysis Core Facility of the Central European Institute of Technology. Together, we work on the application of learned indexing to searching in protein structures produced by Alphafold.
