Do I still need to de-identify sensitive data when using gretel-synthetics?

Gretel synthetics will memorize and replay repeated data that it observes in the training set. When anonymizing sensitive identifying data types within a dataset, such as fields containing social security or credit card numbers, it is best to anonymize data as best as possible before training the synthetic model. Gretel helps you automate this process with our data labeling APIs and transformation SDKs.
