Fig. 1: Illustration of the polymer space and the learning framework.

a The polymer space and molecular dynamics simulation workflow. b Ionic conductivity as a function as simulation time from six independent 5 ns MD runs for the same polymer, showing the random errors caused by the amorphous structure initialization. c Ionic conductivity as a function as simulation time for five different polymers, showing the long simulation time needed for convergence. (Polymer structures for (b, c) are provided in the supplementary information.) d Multitask learning framework to reduce the random and systematic errors from MD simulations.
