A temporal case-based reasoning approach for performance improvement in intelligent environmental decision support systems Open
One of the major problems when designing control and supervision systems for environmental systems is the need to be adapted to the particularities of each system. The use of Artificial Intelligence (AI) techniques instead of classical con…

Optimizing Online Time-Series Data Imputation Through Case-Based Reasoning Open
When working with Intelligent Decision Support Systems (IDSS), data quality could compromise decisions and therefore, an undesirable behaviour of the supported system. In this paper, a novel methodology for time-series online data imputati…
