Alexander Artikis

Dr. Alexander Artikis is an Associate Professor of Artificial Intelligence at the University of Piraeus and a Research Associate at the National Centre for Scientific Research (NCSR) "Demokritos". He leads the Complex Event Recognition (CER) group, focusing on symbolic and probabilistic approaches to event recognition and forecasting.

• University of Piraeus (2025–present)
• NCSR Demokritos (2017–present)
• Complex Event Recognition Group (2017–present)

His research spans Artificial Intelligence and Distributed Systems, with a focus on:

• Complex Event Recognition (CER): Developing logic-based systems for detecting events in real-time data streams
• Event Calculus: Creating probabilistic and incremental versions for runtime reasoning
• Multi-Agent Systems: Modeling norm-governed interactions
• Maritime Informatics: Applying CER to vessel trajectory analysis and fleet management

Key publications reveal trends in:

• Neuro-symbolic forecasting models combining deep learning and logic-based reasoning
• Symbolic automata with memory for pattern detection
• Online learning techniques for dynamic event rule generation
• Tensor-based formalizations for efficient temporal reasoning
• Handling uncertainty in real-time maritime data streams
• Optimizing memory usage for scalable stream processing

He contributes to open-source tools like RTEC (Run-Time Event Calculus) and holds a European patent on complex event forecasting. His work addresses challenges in:

• Proactive decision-making systems
• Knowledge Graph consistency
• Hybrid human-machine discovery of movement patterns
• Big Data analytics for time-critical applications
