I tried to find more information about NVIDIA's deep learning anti-aliasing techniques but did not have much luck.
"NVIDIA researchers used AI to tackle a problem in computer game rendering known as anti-aliasing. Anti-aliasing is another way to reduce noise — in this case, the jagged edges in the partially rendered images. Called “jaggies,” these are staircase-like lines that appear instead of smooth lines. (See left inset in image below).
NVIDIA researchers Marco Salvi and Anjul Patney trained a neural network to recognize these artifacts and replace those pixels with smooth anti-aliased pixels. The AI-based technology produces sharper images than existing algorithms." (source)
From this, I found a paper about detecting aliasing but not on fixing it (link).
