Fig. 4: PFESS approach for synergistic effects between X- and Y-metals.

a Schematic diagram of training 1D–6D descriptors through our proposed PFESS method. b RMSE for the best descriptors or mean RMSE for CV10 by PFESS method with different dimensions. c ∆G(*OH), d UL(CRR), or e UL(NRR) as linear functions of ϕxy on X-Y sites (blue shaded part represents the error bar for different coordination environments).
