Smart grid load forecasting using online support vector regression
TL;DR: This work demonstrates the suitability of online support vector regression (SVR) method to short term power load forecasting and thoroughly explore its pros and cons, and presents a comparison of ten state-of-the-art forecasting methods in terms of accuracy on public Irish CER dataset.
Proceedings ArticleDOI
Adaptive Time Series Forecasting of Energy Consumption Using Optimized Cluster Analysis
Peter Laurinec,Marek Loderer,Petra Vrablecová,Mária Lucká,Viera Rozinajová,Anna Bou Ezzeddine +5 more
TL;DR: For energy consumption forecasting, an improvement of incremental adaptive power load forecasting methods is presented by performing cluster analysis prior to forecasts by carrying out the cluster analysis before applying predictive techniques.
Journal ArticleDOI
Supporting Semantic Annotation of Educational Content by Automatic Extraction of Hierarchical Domain Relationships
Petra Vrablecová,Marián Šimko +1 more
TL;DR: Despite the fact that utilization of the method does not necessarily improve the speed of the domain model creation nor does it reduce the overall difficulty of the task, a significant improvement in the quality of resulting domain models has been observed.
Book ChapterDOI
Computational Intelligence in Smart Grid Environment
Viera Rozinajová,Anna Bou Ezzeddine,Marek Loderer,Jaroslav Loebl,Róbert Magyar,Petra Vrablecová +5 more
TL;DR: This chapter presents one way of incorporating computational intelligence into smart grid environment by involving advanced methods of data analysis and optimization and proposes solutions, which deal with stream and online processing as well as adaptivity of the proposed solutions.
Book ChapterDOI
Application of Biologically Inspired Methods to Improve Adaptive Ensemble Learning
Gabriela Grmanová,Viera Rozinajová,Anna Bou Ezzedine,Mária Lucká,Peter Lacko,Marek Loderer,Petra Vrablecová,Peter Laurinec +7 more
TL;DR: Different weighting schemes of predictive base models including biologically inspired genetic algorithm (GA) and particle swarm optimization (PSO) in the domain of electricity consumption are investigated to improve the performance of ensemble learning in the presence of different types of concept drift that naturally occur in electricity load measurements.
