Abstract
An inverse mapping method called PCB (principal component backing), in which the point representing an unknown sample from a low‐dimensional principal component subspace is back‐projected to the high‐dimensional original feature space, is proposed. Two sorts of boundary conditions, non‐linear inverse mapping and linear inverse mapping, are used to obtain an accurate solution in the PCB method. The method is applied to the material design of high‐Tc superconductors, predicting the composition and process conditions for the synthesis of F‐doped Bi‐based materials. Samples in the ‘optimal’ region with the highest Tc of the Bi‐based ceramics have been predicted.
