Synthetic data (synthetische data) is een begrip binnen de industriële digitalisering en innovatie & toekomsttrends.
Definitie
Synthetic data (synthetische data) is kunstmatig gegenereerde data die de statistische eigenschappen en patronen van echte data nabootst, zonder daadwerkelijke gevoelige informatie te bevatten. In de metaalindustrie wordt het gebruikt voor machine learning training, process simulation en testing zonder exposure van proprietary manufacturing data.
Kenmerken
- Artificial generation: Created using algorithms, niet collected van real systems
- Statistical equivalence: Mimics real data distributions en correlations
- Privacy preserving: Bevat geen actual sensitive manufacturing data
- Scalable generation: Can produce large volumes voor training purposes
- Controlled variation: Specific scenarios en edge cases kunnen worden gesimuleerd
- Quality metrics: Fidelity, utility en privacy measures voor validation
- Format flexibility: Structured, unstructured, time-series data generation
- Compliance friendly: Helps meet data protection regulations
