The significance of the original image was in verifying that our laws and models of black holes truly reflected reality.
This AI enhanced image used simulations to guess at the missing data. Doesn’t that defeat the purpose of the black hole image in the first place?
This situation reminded me of when Samsung used AI and professional moon photos to insert details into blurry photos of the moon taken on their camera [0]. Isn’t that image no longer a current, true representation?

- mdp2021 3y agoAre you sure that that is what "PRIMO" does? Have you read the article? "PRIMO" does not seem to be a "plausible detail adder", but a "data interpreter".
- sandgiant 3y agoPRIMO is a way to fit models to the data in image-space. Since the models are very expensive to run it's not feasible to sample the model parameters directly in order to find a fit to data. Instead they take a library of model outputs and parameters and do a principle component analysis in image-space. This allows them to very cheaply generate new samples without running the complete simulation for each new set of parameters. Principle component analysis is an old school analytical numerical method and has nothing to do with AI.
