Hi Alain,

I don't think it's that simple... Here's an article about it:
https://www.intel.com/content/www/us/en/developer/articles/technical/intel-employs-ml-to-create-graphics.html#gs.mshzmp


I haven't read through the whole thing, but they used machine learning somehow.
My guess is that they fed a neural network image pairs: one completely converged
(noise-free) image, and the same scene, but really noisy. The system eventually
learned that when the noise looks a certain way, it's meant to turn out a
certain way.
