Does ODA Learn Over Time? Managing Ongoing Training and Optimization

Summary:

Dear All, I am new to ODA I have below query. Can someone please address them.

Once Oracle Digital Assistant (ODA) is configured, will it continuously improve over time based on user interactions from Fusion HCM, or will we need to manually update training phrases in the ODA instance on a recurring basis?

If it does improve automatically, will it follow the trained model, ensuring responses are limited to the defined skills, intents, and user security roles?

If not, why is manual intervention still necessary despite ODA being an AI-driven solution? Also, what is the recommended frequency for reviewing and updating the training data to maintain optimal performance?"
