It analyzes data to arrive to a qualitative determination (the "shape"), also enabling further computation based on it (the mass): that counts as AI.
"Otherwise you would have had to figure it out through your own direct intellectual effort" counts as AI.
- sandgiant 4y agoI'm not sure what you mean, but the techniques they are using are not new and are not related to artificial intelligence. They use a 120 year old numerical technique to "super-sample" their expensive simulations, which allows them to "fit" the simulations to data in a robust way. They do the calculations in a computer because there are too many numbers to do it on paper. That does not mean it has anything to do with AI.
- mdp2021 4y agoI understood that PCA is there as one of the employed ways to augment the input data, then other ways are employed for the analysis of the data - that is where the literal "Artificial Intelligence" happens. -- Edit: see also, for example: > In contrast, PCA finds correlations between different regions in Fourier space in the training data, which allows PRIMO to generate physically motivated inferences for the unobserved Fourier components ...inferences are drawn on the interpolated data.
