What the article says around this equation
with drawn from a standard normal distribution and the trained network. Generating a structure then means starting from coordinates that are almost pure noise and repeatedly applying the trained denoiser, each pass nudging the atoms closer to a physically coherent arrangement, across many scales at once — from the local geometry of a single ring to the global fold of an entire complex [ 2 ] . Both AlphaFold2 and AlphaFold3 were trained on structures deposited in the Protein Data Bank; AlphaFold3’s training data was cut at structures released before 30 September 2021, supplemented by sequence databases including UniRef90, Uniclust30, and BFD, and RNA-specific databases…
