a Schematic diagram for the reverse design. b A typical example of a CD spectrum predicted with designed parameters vs. experimentally verified parameters. Inset: the error distribution of predicted vs. measured gabs values of 20 samples. The mean absolute error (MAE), root mean squared error (RMSE) and coefficient of determination (R2) of the validation data are 0.09, 0.15, and 0.95, respectively. c, d Examples of experimental realization of inverse design for a target dissymmetry factor gabs = 1.5 at 500 nm. Films created with multiple sets of parameters can achieve this goal (c parameters generated by inverse design, d curves of experiment (solid lines) vs. prediction (dashed lines)). e Same as c, d but the target is set to gabs = 2, the theoretical limit, at 400 nm, 500 nm, 600 nm, and 700 nm. The reverse network provides the best available answer for each target.
