Learning Automata-Based Complex Event Patterns in Answer Set Programming

no code implementations31 Aug 2022 Nikos Katzouris, Georgios Paliouras

Complex Event Recognition and Forecasting (CER/F) techniques attempt to detect, or even forecast ahead of time, event occurrences in streaming input using predefined event patterns.

Artificial Intelligence Empowered Multiple Access for Ultra Reliable and Low Latency THz Wireless Networks

no code implementations17 Aug 2022 Alexandros-Apostolos A. Boulogeorgos, Edwin Yaqub, Rachana Desai, Tachporn Sanguanpuak, Nikos Katzouris, Fotis Lazarakis, Angeliki Alexiou, Marco Di Renzo

In more detail, a fast and centralized joint user association, radio resource allocation, and blockage avoidance by means of a novel metaheuristic-machine learning framework is documented, that maximizes the THz networks performance, while minimizing the association latency by approximately three orders of magnitude.

Distributed Online Learning of Event Definitions

1 code implementation5 May 2017 Nikos Katzouris, Alexander Artikis, Georgios Paliouras

Logic-based event recognition systems infer occurrences of events in time using a set of event definitions in the form of first-order rules.

Activity Recognition Inductive logic programming

Online Learning of Event Definitions

1 code implementation30 Jul 2016 Nikos Katzouris, Alexander Artikis, Georgios Paliouras

The Event Calculus is a temporal logic that has been used as a basis in event recognition applications, providing among others, direct connections to machine learning, via Inductive Logic Programming (ILP).

Incremental Learning of Event Definitions with Inductive Logic Programming

1 code implementation24 Feb 2014 Nikos Katzouris, Alexander Artikis, George Paliouras

Ideally, systems that learn from temporal data should be able to operate in an incremental mode, that is, revise prior constructed knowledge in the face of new evidence.
