Feinabstimmung

AI Center includes the capability of fine-tuning ML models using data that has been validated by a human using Validation Station.

Da Ihre RPA Workflow Dokumente mit einem vorhandenen ML-Modell verarbeitet, können einige Dokumente eine menschliche Validierung mithilfe der Aktivität Present Validation Station erfordern (verfügbar für „Attended Bots“ oder im Browser mithilfe von Orchestrator Action Center).

The validated data generated in Validation Station can be exported using Machine Learning Extractor Trainer activity, and can be used to fine-tune ML models in AI Center.

Es wird nicht empfohlen, ML-Modelle von Grund auf (d. h. das ML-Paket von DocumentUnderstanding) mit Daten aus der Validation Station zu trainieren, es sei denn vorhandene ML-Modelle (einschließlich out-of-the-box Modelle) sollen fein abgestimmt werden.

For the detailed steps involved in fine-tuning an ML model see the Import Documents section of the Data Manager documentation.

Wichtig:

It if often wrongly assumed that the way to use Validation Station data is to iteratively retrain the previous model version, so the current batch is used to train package X.1 to obtain X.2. Then the next batch trains on X.2 to obtain X.3 and so on. This is the wrong way to use the product. Each Validation Station batch needs to be imported into the same Data Manager session as the original manually labeled data making a larger dataset, which must be used to train always on the X.0 ML Package version.
