Memory of diffractive networks. a After being trained for 100 epochs, all the finalized networks (n = 1, 10, 15 and 20) were compared by calculating the average PCC values over unknown objects distorted by all the known diffusers (solid line). Dashed line: the average PCC value over unknown objects distorted by diffusers indexed as 1–99n. Inserts: the same plot zoomed into the last 50 diffusers. b PCC values of each finalized network tested with images distorted by 10n diffusers used in last 10 epochs in training (n = 1, 10, 15 and 20, respectively) and 20 new random diffusers (never seen before). The error bars reflect the standard deviation over different diffusers
