Is this painting a Raphael or not?

This is so not a Raphael it is painful. Raphael was particularly known for his convincingly realistic babies (and for breaking with the tradition of making the child Christ look like a tiny, dignified adult). These babies look nothing like Raphael's babies in any of his many Madonnas, and are expressly tiny dignified adults.

Relying too much on ML models seems risky. If an AI model is established as authoritative in the field, a forger who gets access to the model data could create adversarial fakes that look absolutely genuine to the AI. Bribe the right person and nobody knows that the ML data has leaked, so the fake’s credibility isn’t easily challenged.

AI fine art forgery detection is the way a certain important character in Horizon: Forbidden West made her initial reputation and fortune.

Whoever painted the work, the picture is clearly too ugly to bother including a decent photo of it in the article. No-one cares what it looks like, and everyone cares about what name they can attach to it.

[edit: I might be too harsh, I'm reading through the archive.ph link and maybe that is dropping some of the images?]
