FERN with Modes
Learn about mode-based FERN that lets you tailor AI-powered matching for every data‑quality goal.
What is FERN?
Flexible Entity Resolution Network (FERN) is Reltio’s AI‑powered matching engine. It augments traditional match rules with large‑language‑model intelligence so you can detect additional duplicates.
Why use modes?
- Control the outcome: Pick the mode that matches your goal — reviewing known pairs, discovering new ones, or combining both — so results line up with your business priorities.
- Match your workflow: Data stewards can focus on high-priority candidates, while discovery teams can surface additional matches that rules may miss.
- Configure in one click: Each mode comes pre-labeled and ready to use, so you're up and running fast and can fine-tune only when needed.
