Fig. 2: Illustration of materials structure–property factorization.

Representative measured I–E patterns in the Bi–Cu–V oxide composition space are shown with red and green fill color indicating negative and positive photocurrent, respectively. This set of photocurrent data is modeled as the sum of contributions for each phase, where the composition map of the contribution of each phase is determined by the product of a representative I–E pattern and the respective phase concentration map from DRNets.
