Our research group focuses on software engineering, evolutionary computing, multi-agent systems, machine learning, and complex networks analysis. We actively collaborate with academic institutions and industry partners to develop solutions supporting homeland security investigation and criminal analysis. Additionally, we specialize in social network analysis and mobile robot systems.

The group • Different areas of interest: software engineering, evolutionary computing, multi-agent systems, machine learning, complex networks analysis, mobile systems... • Active cooperation with academic institutions in Poland and Abroad (e.g. Cracow Institute of Technology, UTBM France, ESIGETEL France, Florida Inst. of Technology USA, George Mason University, USA...) • Active cooperation with industry and government agencies in Poland (e.g. Wasko SA, FIDO Intelligence, Gridwisetech, Polish Police, Polish Border Guard, Polish Platform for Homeland Security...). • Quasi-commercial specialization: solutions supporting homeland security investigation.
Criminal analysis support • Following the demand expressed by public security agencies, different criminal-analysis tools are constructed. • GSM and financial data visualisation and analysis (LINK and Mamut tools) • Sophisticated GUI research (touchscreen and MS Kinect based) • Pattern searching algorithms 4
Complex network analysis • Complex network constructed based on e.g. GSM bilings or blogosphere comments • Identification of roles in social network • Analysis of static and dynamic complex networks • Public security oriented applications 5
Social network analysis • Example: Identification of groups in blogosphere (salon24) with comment based sentiment counting model • Calculated mean values for all stable groups in time slots, for C • CPM parameter k=3: • Social Network Analysis • Identification of groups and key members • Analysis and prediction of group dynamics • Application domain: Analysis of social media (blogosphere - salon24.pl, Twitter), and data about phone calls • Different models of blogosphere (posts, comments, content/sentiment) Example:Stability of discussed topics (post tags)
Mobile robots • Mobile robots laboratory founded in 2004. • Multi-robot systems research (FIRA robot soccer). • Autonomous moving robots. • Agent-based multi-robot systems. • Multi-robot simulation.

Agent-based computing • Hybrid computing systems utilizing the notion of agency • Distributed component-oriented computing platforms (AgE) • Optimization and simulation related applications • Nature-inspired computing 9
Agent learning • Reinforcement and supervised learning in agent-based system • comparison of selected algorithms • supervised sometimes better than reinforcement learning • Hybrid algorithms • classifier can be used to make space more compact for reinforcement learning • Sharing learned knowledge 10
