The PATRAS research group is working on the following research aspects:

+ Pattern recognition in various security and safety applications
+ Cyber security
+ Data mining and pattern extraction,
+ Challenges in machine learning (e.g. lifelong learning, concept drift)
+ Big data analytics and visualisation
+ Image processing (e.g. biometrics, object detection and identification)
+ Data analysis and correlation


The President of the Republic of Poland has signed the nomination of Prof. Michał Choraś, awarding him the professor title in December. Congratulations!

The SWAROG project commenced, and the first partner meeting has been held in Bydgoszcz in December.
