KETTY supports DynaWorks®Â databases
SATE's software tool, KETTY (Knowledge Extraction from TelemeTrY) now supports Intespaceâ€™s DynaWorks® databases, granting a smooth integration between the two software environments.
This, on one side, enables KETTYâ€™s users to import data coming directly from DynaWorksÂ®â€™ databases. On the other side it enables DynaWorksÂ®â€™ users (with an add-on KETTY license) to perform additional analysis, including automatic:
- Extraction of synthetic characteristics of the monitored data (system characterization);
- Evaluation of the system behaviour, by the identification of subsystems or components with novel behaviour, ordered by priority score (novelty detection);
- Determination of cause-effect relationships between parameters of the system that may not be known a priori (behaviour interpretation).
without the need for a priori knowledge about the system.
