Wayeb: a Tool for Complex Event Forecasting
Elias Alevizos, Alexander Artikis, Georgios Paliouras
Complex Event Processing (CEP) systems have appeared in abundance during the last two decades. Their purpose is to detect in real-time interesting patterns upon a stream of events…
Event Forecasting with Pattern Markov Chains
Elias Alevizos, Alexander Artikis, Georgios Paliouras
We present a system for online probabilistic event forecasting. We assume that a user is interested in detecting and forecasting event patterns, given in the form of regular expres…
Symbolic Automata with Memory: a Computational Model for Complex Event Processing
Elias Alevizos, Alexander Artikis, Georgios Paliouras
We propose an automaton model which is a combination of symbolic and register automata, i.e., we enrich symbolic automata with memory. We call such automata Register Match Automata…
Semi-Supervised Online Structure Learning for Composite Event Recognition
Evangelos Michelioudakis, Alexander Artikis, Georgios Paliouras
Online structure learning approaches, such as those stemming from Statistical Relational Learning, enable the discovery of complex relations in noisy data streams. However, these m…
The Complex Event Recognition Group
Elias Alevizos, Alexander Artikis, Nikos Katzouris +2
The Complex Event Recognition (CER) group is a research team, affiliated with the National Centre of Scientific Research "Demokritos" in Greece. The CER group works towards advance…
