We optimized the parameters for the set of lipids over 600 epochs, as shown in Fig. . ) are shown. The panel "Average" contains the mean loss across all the systems, which is the quantity minimized during the optimization procedure (Equation ). 600 epochs. For most systems, the individual loss value decays in the first 400 epochs and then oscillates around a minimum, usually well below 1. For DMPC, we can see that the loss increases in the first 100 epochs, and only then descends, indicating that the starting parameters were already good for this particular system. However, these parameters were not transferable to other systems, especially in the PG and PE series, which show starting losses above 1.
