You get the resolution but not the light capturing capability of a big telescope. The event horizon telescope had to do a lot of machine learning trickery to get an image. Also, as far I understand, it's much more difficult to do this at the wavelength of visible light.
- PopePompus 3y agoThe EHT has used machine learning techniques, but those were not required to get an image that shows the shadow of the black hole. Just using the "clean" algorithm for deconvolution yielded an image showing the shadow, and that algorithm has been in use for radio interferometry for over 40 years, and has nothing whatsoever to do with machine learning.
- rqtwteye 3y agoI watched a presentation by a researcher that worked on the EHT. She pointed out that there was a lot of machine learning to rule out wrong pictures. It’s not simple interferometry.
- PopePompus 3y agoI am also a member of the EHT project. I'm not saying no machine learning was used by EHT team members. I'm saying that you can process the 2017 EHT data using standard radio interferometry techniques, and get an image showing the M87 black hole shadow without machine learning or any other type of AI
