What is synthetic data in banking?

Artificial profiles mimicking real customer behaviors, generated via GANs or VAEs from stats, not identities – lets banks train recs without GDPR/CCPA risks.

Does synthetic data really match real recommendation accuracy?

Yes, studies show 95-98% fidelity in CTRs and patterns, with that German bank holding steady post-switch.

Will synthetic data replace all personal data use?

Not fully – outliers and drifts loom, but it's the go-to for high-risk personalization in regulated sectors.
