[optional] Although models developed on AI generated synthetic will yield similar results in comparison to when developed on original data, it is possible to later score the models on the original data.
The benefit: instead of bringing the original data to your development team to develop the model, you will now be able to bring the developed models to the data. Thereby, your developers will never see the actual data.
Moreover, this allows your internal, or maybe even external organization, to explore and test hypothesis on synthetic data. Then, only when it makes sense, one could score the relevant developed models on the original data. For scoring, you will exactly know which data is relevant and which models makes sense to score, which allows you to minimize the use of original (sensitive & personal) data.
